35 In concluding that no action in trespass or false imprisonment might lie against officers of the AFP executing a warrant the Master had regard to the judgment of Lord Diplock (delivering the judgment of the majority) in Maharaj v Attorney-General of Trinidad and Tobago (No.2) [1979] AC 385 at 397:
"No action in tort would have lain against the police or prison officers who had arrested or detained him since they would have acted in execution of judicial process that was valid on its face."
36 In Maharaj v Attorney-General of Trinidad and Tobago a barrister appearing before the High Court of Trinidad and Tobago was committed to prison for seven days upon the order of the trial judge for contempt of court. That order was subsequently found to have been unlawful. This did not expose the police who arrested and detained the barrister, pursuant to the process duly issued, to liability in an action in tort.
37 I am persuaded that the Master erred in concluding that as a matter of law there could not be a claim brought by the second plaintiff for false imprisonment in circumstances where the members of the AFP were executing valid judicial process. In Trobridge v Hardy (1995) 94 CLR 147 Fullagar J at 152 observed:
"The mere interference with the plaintiff's person and liberty constituted prima facie a grave infringement of the most elementary and important of all common law rights. It was for the defendant to justify, if he could, by reference to his office or otherwise."
38 In Myer Stores Ltd v Soo [1991] 2 VR 597 Murphy J observed at 599:
"Even more recently, in this Court, in the case of Carnegie v State of Victoria (unreported, Supreme Court of Victoria, Full Court, 14 September 1989) it was reaffirmed that:
The gist of the action of false imprisonment is the mere imprisonment. As a result the plaintiff carries the burden of establishing no more than imprisonment. He need not prove it was unlawful. If imprisonment is proved it is for the defendant if he is to escape liability to prove a lawful justification for the imprisonment either at common law or by statute."
39 The Master proceeded upon the footing that there was in existence a warrant valid on its face. This reflected the way the matter was conducted before her. In the light of Mr Robinson's frank indication as to the results of the Commonwealth's inquiries it may be that the assumption that there was a warrant which was valid on its face is not correct. Be that as it may, it seems to me to put the proposition too broadly to assert, "There cannot be a trespass or false imprisonment where the police are executing valid judicial process" (judgment at [17]). It is necessary to determine the scope of that which is authorised by the warrant.
40 On the hearing of the appeal Mr Robinson accepted that on their face [17] and [18] of the Master's judgment were expressed in terms which are too absolute. Mr Robinson submitted that the proper proposition of law would be in terms, "That if there was a valid warrant and the police complied entirely with it, then they would in effect have a defence to a tort in respect of matters contemplated by the warrant." That seems to me to be a fair concession.
41 By its motion the Commonwealth sought orders staying or dismissing the proceedings generally pursuant to Pt 13 r 5 of the SCR or, alternatively, striking out the SOC as having a tendency to cause prejudice, embarrassment or delay in the proceedings (or being otherwise an abuse of the process of the Court) pursuant to Pt 15 r 26(1) of the SCR. It was not in issue on the hearing of the appeal that the SOC in its present form is defective and susceptible to causing prejudice, embarrassment and delay. The plaintiffs took issue with the Master's refusal to allow them to replead their claim.
