Petitioners also pray for a declaration that byelaw no.9 framed by Respondent No.1 is ultra vires the provisions of Public Premises (Eviction of Unauthorised Occupants) Act, 1971 and/or the Major Port Trusts Act, 1963 (read with erstwhile Bombay Port Trusts Act, 1879). 3.

Petitioners claim to be in possession since many years anterior to 1st April, 1962, the datum line prescribed by the Municipal Corporation for tolerating commercial premises. The properties occupied by the petitioners are assessed for taxes and they are continuously paying property tax to the Mumbai Municipal Corporation. 4. Petitioners have also been issued a license under the Maharashtra Shops and Establishments Act for carrying out the business. Most of them are also regularly paying professional tax. Petitioners contend that abruptly notices have been issued by Respondent No.1 calling upon them to vacate the premises within twelve hours, failing which, they are threatened with demolition of structures.

Petitioners claim that they have been threatened with deprivation of their right to earn their livelihood and shelter by the proposed action of eviction from the business premises occupied by them since long.
