If summary judgment is given to one party on his claim, it must also be given on a counterclaim made on the same basis by the defendant. The principle that a party to litigation cannot ‘approbate and reprobate’ (or ‘blow hot and cold’) can curtail a party’s theoretical freedom to plead wholly inconsistent cases as alternatives. It is imported into English law from Scotland, and although it covers much the same ground as elective waiver and waiver by estoppel, it may be rather more flexible.
As to the Lion Laboratories case: ‘In my judgment, that decision has no application to the present case. Where that type of defence is put forward it permits the publication of secret information which it is in the public interest should be known. It does not apply to information of the kind which it may be of interest to the public to know. Moreover, the basis of the defence being that the public needs to know, the whole basis for the defence goes once such information has been disclosed to all, i.e. by one paper. There is no further requirement of public interest that another paper should be able to repeat the revelation of that information.’
