Third party is defined in rule 3 to include any person joined as a fourth or subsequent party. The term therefore operates as a label for any party brought into the action by a defendant (or downstream party) who claims contribution or indemnity. The rule does not alter the underlying substantive law of contribution or indemnity; it merely provides the procedural machinery for bringing such claims within the existing action.

Contribution and indemnity are the two grounds on which a third party notice can be filed. Contribution refers to a claim that the third party should share the burden of any judgment against the defendant, typically under principles of joint liability or proportionate responsibility. Indemnity refers to a claim that the third party is legally obliged to bear the entire amount of the judgment, often by contract, statute or operation of law. The rule does not define these terms; they draw their content from the general law and the Law Reform (Miscellaneous Provisions) Act 1946.

Joinder is the process by which a third party becomes a party to the proceeding. It is initiated by filing a third party notice with the registrar, not by issuing a separate plaint or summons. The notice must contain the same particulars that would be required if the claim were sued on separately. The registrar then signs copies, serves one on each plaintiff (unless the action has been set down for hearing under the ordinary summons procedure, in which case copies are returned to the defendant for service), and returns other copies to the defendant for service on the third party.

Stay of proceedings under rule 6 operates automatically when a defendant who has filed a notice of defence also files a third party notice. The stay lasts until the third party files a notice of defence or until 28 days after service of the third party notice, whichever comes first. This pause prevents the plaintiff from pressing ahead before the third party issue is ready. The plaintiff can apply to have the stay lifted if the third party notice is not served within a reasonable time.

Deemed admission is a key default mechanism. If a third party does not file a notice of defence within 28 days of service, the third party is deemed to have admitted the whole of the defendant’s claim. The court may then, on the defendant’s written application and without further notice to the third party, enter judgment against the third party. This creates a strong incentive for a third party who wishes to contest the claim to file a defence promptly.

Separate trials are available under rule 11. If the court considers that trying the main action and the third party issues together would embarrass, delay or be otherwise inconvenient, it may order separate trials or make any other order it thinks fit. This preserves the court’s ability to manage its list and avoid prejudice.

Costs powers under rule 16 are broad. The court can treat the third party as if they were a plaintiff or defendant for costs purposes, enabling it to order a third party to pay the plaintiff’s costs directly, or to order the defendant to pay the third party’s costs, or any other allocation that the justice of the case requires.

The rule directly affects defendant, plaintiffs and third parties (including fourth and subsequent parties) in civil claims commenced in the Court of Petty Sessions. Its primary beneficiary is a defendant who believes that another person is legally responsible, whether in whole or in part, for the plaintiff’s claim. Such a defendant gains the ability to bring that person into the same proceeding without having to wait for an outcome and then commence a separate action. This reduces the defendant’s litigation risk and transaction costs, but it also imposes a set of procedural obligations and deadlines that must be observed on pain of losing the right to join.

Plaintiffs are affected because once a third party notice is filed, the plaintiff’s action is automatically stayed until the third party files a defence or 28 days elapse. The plaintiff cannot push the case to judgment during that period. However, the plaintiff can apply to remove the stay if the defendant delays service. The plaintiff also gains the benefit of having all potentially liable parties in the one proceeding, which may improve the prospect of recovery or simplify enforcement.

Third parties receive a notice that effectively makes them a party to the action. They are required to file a notice of defence within 28 days; if they do not, they are deemed to have admitted the defendant’s claim and may have judgment entered against them without further hearing. Third parties have the same rights and are subject to the same liabilities as if they had been sued in a separate action. They can contest both the plaintiff’s claim against the defendant (on which the defendant’s claim depends) and the defendant’s claim against them.

Fourth and subsequent parties are brought in by the same procedure, with each preceding party acting as the defendant and the next as the third party. This chain can lengthen the litigation and multiply the parties, increasing complexity and cost, but it can also ensure that all contribution and indemnity issues are resolved in one proceeding.

Registrars perform essential administrative tasks: signing copies, serving notices on plaintiffs, returning copies to defendants, listing actions for hearing after a third party defence is filed. Bailiffs, commercial agents, attorneys, employees of an attorney’s office, and persons in the permanent and exclusive employ of the defendant may serve third party notices, broadening the service options beyond the court bailiff.

The court itself is affected because it must manage the joinder, stay, trial directions, possible separate trials, and costs. The court is given substantial discretion to tailor the procedure to the circumstances, which adds to its workload but also allows it to prevent abuse.

Defendant’s rights. A defendant who claims contribution or indemnity from any person has the right to file a third party notice within the time limits specified in rule 5(1). The right is not absolute; it is confined to claims for contribution or indemnity, not any other cause of action the defendant may have against the third party. The defendant can also make such a claim against a co-defendant using the same procedure (rule 9). Once the third party is joined, the defendant can apply for judgment against the third party if the third party defaults in filing a defence (rule 12). The defendant also has the right to have proceedings stayed automatically until the third party issues are ready (rule 6). The defendant can serve the notice using a range of persons (rule 6(2)), not just bailiffs.

Defendant’s duties. The defendant must file the notice within the time limit applicable to the type of summons. The notice must contain the same particulars as would be required if the claim were separately sued (rule 5(2)). The defendant must ensure that, when serving the notice on the third party, a copy of the summons and a copy of every other document filed before the notice is filed are also served (rule 7(1)). The person effecting service must file an affidavit of service as soon as practicable and notify each other party (other than the defendant if service was by bailiff) of the date of service (rule 7(2)). The defendant cannot enforce any judgment against the third party until the plaintiff’s judgment against the defendant has been satisfied, unless the court orders otherwise (rule 10(3)). That condition is a significant restriction on the defendant’s right to recover.

Third party’s rights. The third party has the same rights as if they had been sued in a separate action. They can file a notice of defence (rule 8) specifying whether they dispute the plaintiff’s claim against the defendant, the defendant’s claim against them, or both. They can participate in the trial to the extent directed by the court (rule 10(1)). They can seek separate trials if joinder would cause embarrassment or delay (rule 11). They can also join a fourth party if they have a contribution or indemnity claim against someone else (rule 13).

Third party’s duties. The third party must file a notice of defence within 28 days of service. Failure to do so results in a deemed admission of the whole of the defendant’s claim and potential entry of judgment without further notice (rule 12). If the third party wishes to contest, they must actively file a defence and specify which claims are disputed.

Plaintiff’s rights. The plaintiff can apply to the court to remove the stay of proceedings if the third party notice is not served within a reasonable time (rule 6(3)). The plaintiff can also seek costs against the third party under rule 16, and can enforce any judgment against the defendant even though third party issues are still pending (the plaintiff’s rights against the defendant are not prejudiced by a co-defendant claim under rule 9). The plaintiff is entitled to receive a copy of the third party notice from the registrar (rule 5(3)(b)) and to be notified of service dates (rule 7(2)).

Registrar’s duties. Upon filing, the registrar must sign the copies, serve one on each plaintiff (unless the action is set down for hearing under the ordinary summons procedure, in which case copies are returned to the defendant), and return other copies to the defendant (rule 5(3)). When a third party defence is filed, the registrar must serve copies on the plaintiff and the defendant and, if the action is not already listed for hearing, list it for hearing (rule 8(2), (3)).

The rule creates a set of consequences that operate as penalties for non compliance, though they are procedural rather than punitive in nature. The most significant is the deemed admission under rule 12. If a third party does not file a notice of defence within 28 days after service of the third party notice, the third party is deemed to have admitted the whole of the defendant’s claim. The court may then, on the written application of the defendant and without further notice to the third party, enter judgment against the third party. This is a harsh default: it allows the defendant to obtain a judgment without any hearing on the merits and without the third party having any opportunity to argue. The absence of further notice means the third party may not even know judgment has been entered until enforcement steps are taken. The court can “otherwise order” but the rule does not specify grounds; it is a discretion that may be exercised if the third party has a reasonable excuse or if the defendant’s application is premature. But the burden is on the third party to seek relief, which will likely require an application to set aside the judgment.

Enforcement of any judgment obtained by the defendant against the third party is restricted by rule 10(3). The defendant cannot enforce the judgment until the plaintiff’s judgment against the defendant in the same action has been satisfied. This prevents the defendant from recovering from the third party before paying the plaintiff, which would put the plaintiff at risk if the defendant then failed to satisfy the plaintiff’s judgment. The defendant can apply to the court for an order allowing earlier enforcement; such an order may be made on conditions (rule 10(4)). This condition effectively subordinates the defendant’s claim to the plaintiff’s claim in the enforcement queue, altering the usual right to enforce a judgment immediately.

Costs orders under rule 16 can be used to allocate costs against any party, including the third party. The court can order a third party to pay costs incurred by the plaintiff or the defendant, or to pay costs that would otherwise be payable by another party. This gives the court broad power to penalise a third party for unreasonable conduct, such as failing to defend promptly or defending a claim that should have been admitted. The costs power is supplementary to the general costs provisions of the Courts of Petty Sessions (Civil Claims) Act 1970 and can be exercised as if the third party were a plaintiff or defendant.

If a third party fails to attend trial or comply with court directions, the court may proceed to give judgment under rule 10(2). That judgment would be final between the defendant and third party, and would be enforceable subject to the condition in rule 10(3). The court can also order separate trials (rule 11) if the joinder would embarrass or delay the plaintiff’s action, which effectively penalises a defendant who joins a third party in circumstances that complicate the main action.

There is no fine or contempt provision in the rule; the enforcement mechanism is entirely through judgment, costs and procedural defaults.

The rule is expressly made under the Law Reform (Miscellaneous Provisions) Act 1946, as indicated in the third party notice form. That Act contains substantive provisions on contribution and indemnity between tortfeasors and others, which the rule is designed to facilitate procedurally. The rule does not modify the substantive law of contribution; it only provides the mechanism for bringing such claims in the Court of Petty Sessions.

The rule operates within the framework of the Courts of Petty Sessions (Civil Claims) Act 1970 and the Courts of Petty Sessions (Civil Claims) Rules. Rule 4 provides that the provisions of that Act (excluding sections 22, 23, 23A and 24) and those Rules apply to the joinder of a third party, with appropriate changes of nomenclature: a plaintiff includes a defendant who files a third party notice, a defendant includes the third party, and a plaint or summons includes a third party notice. This incorporation means that all the usual provisions about filing, service, amendment, pleading, evidence, costs, appeal and enforcement under the 1970 Act and its rules apply to third party proceedings unless inconsistent with the specific provisions of this rule.

Specifically, rule 15 deems the filing of a third party notice to be the filing of a plaint and summons for the purposes of sections 34 and 35 of the 1970 Act. Those sections likely deal with the court’s jurisdiction to hear and determine claims and the limitation periods or fees associated with commencing an action. The effect is that the third party claim is treated as a separate action for certain statutory purposes, which may affect the calculation of court fees, limitation periods and the court’s jurisdictional limit.

The rule does not affect the plaintiff’s substantive rights against the defendant. Rule 9 expressly preserves the plaintiff’s rights against any other defendant when a co-defendant claim is made. The stay of proceedings under rule 6 temporarily suspends the plaintiff’s ability to progress the action, but the plaintiff can lift the stay.

The parent Act (1970) has been repealed, but the rule itself is still listed as current. This creates a potentially uncertain interaction: if the enabling Act is repealed but the rule is saved by transitional provisions, the rule may continue to operate. Practitioners must check the current Local Court Act and rules to ensure the third party procedure remains valid, but the text of the rule assumes the 1970 Act is still in force. The form also cites the Law Reform (Miscellaneous Provisions) Act 1946, which is still in force, providing the underlying substantive basis for contribution and indemnity claims.

The rule does not interact with federal laws, other state legislation, or the rules of other courts. It is confined to the Court of Petty Sessions (now Local Court) and does not apply to the District Court or Supreme Court, which have their own third party procedures.

The source text does not record any amendments to this rule since its commencement on 4 April 1977. The editorial note confirms the date of commencement by reference to the Gazette of 11 March 1977. The rule appears to be in its original form, with no amending instruments listed. However, the rule’s continued operation is uncertain because the primary Act it references, the Courts of Petty Sessions (Civil Claims) Act 1970, has been repealed. The rule may have been preserved by subsequent Local Court legislation, but that is not documented in the source. The Law Reform (Miscellaneous Provisions) Act 1946, under which the rule was made, is still in force, but the rule was specifically tied to the now-repealed 1970 Act. This raises a question about the rule’s current legal status. If the rule remains in force by virtue of transitional provisions, no amendment has been made to its text since 1977. The form in Schedule 1 uses the outdated court name “Court of Petty Sessions” and a pre-2000 date format (19__), indicating it has not been updated to reflect the renaming to the Local Court or to modernise references. A modernised equivalent would likely be found in the Local Court Rules, but this rule as written has not been formally amended.

The source text does not refer to any cases. The rule itself is a procedural instrument and does not cite judicial decisions. However, as a long-standing rule that has been in force since 1977, it is likely that courts have interpreted its provisions in the context of Local Court practice. For example, the deemed admission under rule 12 has probably been considered in applications for default judgment against third parties. The court’s discretion to “otherwise order” in that rule has likely been litigated. The condition on enforcement in rule 10(3) may have been tested. The separate trials power under rule 11 has probably been used. The costs power under rule 16 might have been exercised in various ways. But because the source does not name any case, we cannot refer to specific decisions. A deep dive cannot invent cases; it can only note that the rule’s operation over four decades would have generated case law. For the purpose of this analysis, we note that the rule’s provisions are standard and have analogues in higher court rules (e.g., Uniform Civil Procedure Rules 2005 (NSW) Part 20), which have been extensively litigated. But the source does not support any particular proposition about litigation history.

Several traps await unwary practitioners. The time limits for filing a third party notice differ by summons type and are unforgiving. For a default summons, the notice must be filed no later than the notice of defence, or within 14 days after service if no defence is filed. For a special summons, the same but 28 days. For an ordinary summons, the window can close three days before the hearing date, or before the hearing commences if the action is set down. Missing these deadlines likely waives the defendant’s right to join the third party, forcing a separate action. The defendant must know which type of summons was used and track the filing dates precisely.

The stay of proceedings under rule 6 is automatic but only if the defendant has filed a notice of defence. If the defendant has not filed a defence, there is no stay. The plaintiff can then proceed to default judgment against the defendant while the third party notice is pending, potentially complicating matters. Also, the stay expires upon the earlier of the third party filing a defence or 28 days after service. The defendant must ensure service is effected quickly; otherwise the plaintiff can apply to remove the stay.

Service of the third party notice is more onerous than ordinary service. Rule 7(1) requires that at the time of service, the third party must also be served with a copy of the summons and a copy of every other document filed in the action before the notice is filed. Failing to include these documents renders the service ineffective. The person effecting service must file an affidavit of service and notify each other party of the service date. Non compliance with that notification duty may cause procedural chaos.

The deemed admission in rule 12 is a powerful weapon for the defendant but can be set aside by the court. The third party who receives a judgment entered without notice may have to make an application to set it aside, incurring costs. The rule does not set a time limit for such an application, but delay will make it harder. The defendant seeking judgment under rule 12 must use a written application; the rule does not require the defendant to prove service of the notice or the failure to file a defence, but the court will likely require evidence. If service was defective, the judgment will be vulnerable.

The enforcement restriction in rule 10(3) is often overlooked. A defendant who obtains a judgment against the third party cannot enforce it until the plaintiff’s judgment against the defendant is satisfied. This means the defendant cannot use the third party judgment as a set off or as a basis for a garnishee order until the defendant has paid the plaintiff. It also means the third party judgment may sit dormant for a long time. The court may grant an order allowing earlier enforcement, but that is discretionary and may be conditioned on the defendant providing security.

The rule only applies to claims for contribution or indemnity, not to other causes of action such as breach of contract or negligence (unless those underpin the contribution/indemnity claim). A defendant who tries to join a third party on a different basis may have the notice struck out.

The rule uses the nomenclature of the Court of Petty Sessions, which has been renamed the Local Court. Practitioners filing in the Local Court should confirm that this rule remains in force and has not been superseded by the Local Court Rules 2009 or other instruments. The form in Schedule 1 is outdated and may not be accepted by registrars; a modernised version may be required under current practice notes.

Fourth and subsequent party joinder can create complex chains. Rule 14 applies the same rules to each successive group, but the chain can lead to absurdities if not managed carefully. For example, a fourth party may need to serve a fifth party with documents from the original action, and so on. Each new party must be served with all documents filed before the notice for that level, which can become voluminous.

Costs can be awarded against a third party who is not ultimately liable to the plaintiff. Rule 16 allows the court to treat the third party as a plaintiff or defendant for costs, meaning a third party who unsuccessfully defends the defendant’s claim could be ordered to pay the defendant’s costs, and potentially the plaintiff’s costs as well. This increases the financial risk for third parties.

Compliance depends on which party you are. For a defendant who wishes to join a third party for contribution or indemnity, follow these steps.

1. Identify the right. Ensure the claim against the third party is for contribution or indemnity, not some other cause of action. If the claim is not within that category, the rule does not apply and a separate action will be necessary.

2. Prepare the third party notice. Use Form No 1 in Schedule 1, or a notice to the same effect. Include particulars of the claim as would be required if the claim were sued on separately. State the reasons for the claim. Attach a copy of the plaint and summons and a copy of every other document filed in the action before the notice is filed.

3. File within time. Determine the type of summons: default, special or ordinary. File the notice with the registrar within the applicable window (rule 5(1)). For a default summons, file at or before the notice of defence, or within 14 days of service if no defence. For a special summons, same but 28 days. For an ordinary summons, up to three days before the hearing, or before the hearing commences if the action is set down, or before the application for a hearing date if the action is listed for a call over. Do not file after these deadlines.

4. Arrange service. You may serve the notice by a bailiff, a commercial agent or subagent, an attorney, a person employed in an attorney’s office, or a person in your permanent and exclusive employ (rule 6(2)). The person serving must also serve a copy of the summons and a copy of each other document filed before the third party notice. Service must be effected in the same manner as service of a summons on a defendant (rule 7(1)).

5. File affidavit of service. The person who effects service must file an affidavit of service as soon as practicable (rule 7(2)). They must also notify each party to the action (other than the defendant if service was by bailiff) and the third party of the date of service. Keep a record of that notification.

6. Monitor the third party’s response. The third party has 28 days from service to file a notice of defence. If it does not, you may apply in writing to the court for judgment against the third party without further notice. The application should include evidence of service and the third party’s failure to file. If the third party files a defence, the registrar will serve copies on you and the plaintiff and list the action for hearing.

7. Proceed to trial. The court may direct the third party’s role. Be prepared for a possible application for separate trials if the third party issues complicate the main action. At trial, the court may give judgment between you and the third party. Do not attempt to enforce any judgment against the third party until the plaintiff’s judgment against you has been satisfied, unless you obtain a court order permitting earlier enforcement.

For a third party who receives a notice, compliance involves:

1. Read the notice and attached documents. Understand what the plaintiff claims and what the defendant claims against you.

2. File a notice of defence within 28 days of service. In the defence, specify whether you dispute the plaintiff’s claim against the defendant, the defendant’s claim against you, or both (rule 8(1)). If you do not file, you are deemed to admit the whole of the defendant’s claim and judgment may be entered against you without further notice.

3. Participate in the proceedings. The court may direct the extent of your involvement. You can also join a fourth party if you have a contribution or indemnity claim against someone else.

For a plaintiff faced with a third party notice, compliance is minimal: note the stay of proceedings, and if the defendant delays service, apply to the court to remove the stay. You are entitled to copies of the notice and the third party’s defence.

For registrars, follow the duties in rules 5(3) and 8(2): sign copies, serve on plaintiff, return to defendant, and list for hearing when a third party defence is filed.

Overall, the key to compliance is to act promptly, serve correctly, keep accurate records of service and filing, and be aware of the automatic stay and enforcement restriction. The rule’s time limits and service requirements are strict but the procedure itself is straightforward once the deadlines are met.
