N.Y.C. Charter § 36: Section 36. Local laws; passage.

No local law shall be passed until it shall have been in its final form and upon the desks of the council members at least seven calendar days, exclusive of Sundays, prior to its final passage, unless the mayor shall have certified as to the necessity for its immediate passage and such local law be passed by the affirmative vote of two-thirds of all the council members.

For purposes of this section "electronic means" means any method of transmission of information between computers or other machines designed for the purpose of sending and receiving such transmissions and which: allows the recipient to reproduce the information transmitted in a tangible medium of expression; and does not permit additions, deletions or other changes to be made without leaving an adequate record thereof.
