26 In Squire v Squire [1972] 1 Ch 391 the plaintiff issued a writ and statement of claim against three members of his family and a company alleging a conspiracy to cheat and defraud arising out of a sale of his shares in the company to the defendants. The defendants by their defences denied the allegations. At the trial the plaintiff was granted leave to amend his statement of claim to allege a conspiracy to cause and procure the company to act in breach of duty and unlawfully and the trial was adjourned. No order permitting amendment of the statement of claim was drawn up. However, in an order for security for costs by the plaintiff an order was inserted that the defendants be at liberty to serve on the plaintiff such defences or amended defences to the action as they may be advised. The defendants amended their defences so as to plead laches, acquiescence and limitation of action not previously pleaded. The plaintiffs moved for an order that the defendants should not be at liberty to amend their defences so as to rely upon laches, acquiescence or limitation as a defence to the allegation of fraudulent conspiracy. In the course of hearing that application Goff J corrected that order under the slip rule so that it should refer quite neutrally to service of defences. Before Goff J it was contended for the plaintiff that, while the defendants were entitled by amendment to plead, as amendments consequential upon the amendments to the statement of claim, laches, acquiescence and limitation in respect of the alleged breaches of duty and alleged liabilities, they were not entitled to plead in respect of the fraudulent conspiracy, unless they made a substantive application for leave so to do. The defendants contended that when leave was obtained by the plaintiff to amend the statement of claim this resulted automatically in an unlimited ability in the defendants to amend their defences as they thought fit. Alternatively, the defendants contended that if this was wrong, and their consequential ability to amend was limited to the introduction of matters that have been described as consequential upon the changes introduced into the statement of claim in its amended form, then the plea of laches, acquiescence and limitation was consequential in that sense in respect also of the allegation of fraudulent conspiracy. Goff J ruled against the wider construction advanced by the defendants but concluded that on the narrow approach neither side was wholly correct. Goff J held that the defendants were entitled to plead laches and acquiescence in connection with the conspiracy, but not limitation. Both the plaintiff and the defendants appealed. The defendants asserted that their ability to amend was unlimited and in any event if the narrower approach is correct the whole plea including limitation was available to them as consequential upon the amendments touching fraudulent conspiracy. The plaintiff cross-appealed contending that the Judge should not have allowed the plea of laches and acquiescence in relation to the conspiracy.
