M. Srinivasan JUDGMENT
S.V. Manohar, J.
1. The appellants are the owners of properties in Delhi which are governed by the Delhi Municipal Corporation Act, 1957 or the Punjab Municipal Act, 1911. Prior to coming into force of the Delhi Rent Control (Amendment) Act, 1988, these properties were governed by the Delhi Rent Control Act of 1958.
