§ 19. General grant of powers. 1. Every city is granted power to

regulate, manage and control its property and local affairs and is

granted all the rights, privileges and jurisdiction necessary and proper

for carrying such power into execution. No enumeration of powers in this

or any other law shall operate to restrict the meaning of this general

grant of power, or to exclude other powers comprehended within this

general grant.

2. Whenever the constitutionality of any local law, ordinance, rule or

regulation of a city is brought into issue upon a trial or hearing of

any civil cause of action or proceeding in any court, and the city is

not a party to such action or proceeding, notice shall be served upon

the city in accordance with section one thousand twelve of the civil

practice law and rules.
