“In our view, the above allegation is in no way sufficient to hold that the writ petitioner (respondent here) has explained properly and satisfactorily the undue delay of 20 years which had occured between the alleged taking of possession of his land and the date of filing of writ petition in the High Court. We cannot overlook the fact that it is easy to make such kind of allegations against anybody that too against the State. When such general allegation is made against a State in relation to an event said to have occured 20 years earlier, and the State's noncompliance with petitioners' demands, State may not at all be in a position to dispute such allegation, having regard to the manner in which it is required to carry on its governmental functions. Undue delay of 20 years on the part of the writ petitioner, in invoking the High Court's extraordinary jurisdiction under Article 226 of the Constitution for grant of compensation to his land alleged to have been taken by the Governmental agencies, would suggest that his land was not taken at all, or if it had been taken it could not have been taken without his consent or if it was taken against his consent he had acquiesced in such taking and waived his right to take compensation for it.”
