20. Many civil courts deal with suits for declaration of title and injunction against government, in a casual manner, ignoring or overlooking the special features relating to government properties. Instances of such suits against the government being routinely decreed, either ex parte or for want of proper contest, merely acting upon the oral assertions of plaintiffs or stray revenue entries are common. Whether the government contests the suit or not, before a suit for declaration of title against a government is decreed, the plaintiff should establish, either his title by producing the title deeds which satisfactorily trace title for a minimum period of thirty years prior to the date of the suit (except where title is claimed with reference to a grant or transfer by the government or a statutory development authority), or by establishing adverse possession for a period of more than thirty years. In such suits, courts cannot, ignoring the presumptions available in favour of the government, grant declaratory or injunctive decrees against the government by relying upon one of the principles underlying pleadings that plaint averments which are not denied or traversed are deemed to have been accepted or admitted.”
