In repelling the contention, this Court incidentally observed at page 693 thus: "That the only way in which the notification under Section 4(1) can come to an end is by withdrawal under Section 48(1)" is not correct because "under Section 21 of the General Clauses Act, the power to issue a notification includes the power to rescind it and therefore it is always open to the Government to rescind a notification under Section 4 or under Section 6 and a withdrawal under Section 48(1) is not the only way in which a notification under Section 4 or Section 6 can be brought to an end." In Lt. Governor of H.P. vs Sri Avinash Sharma, (supra) the Court observed at page 151 thus: "Power to cancel a notification for compulsory acquisition is, it is true, not affected by Section 48 of the Act; by a notification under Section 21 of the General Clauses Act, the Government may cancel or rescind the notification issued under Sections 4 and 6 of the Land Acquisition Act.
