N.J. Const. art. IV, § 4, ¶ 6

All bills and joint resolutions shall be read three times in each house before final passage. No bill or joint resolution shall be read a third time in either house until after the intervention of one full calendar day following the day of the second reading; but if either house shall resolve by vote of three-fourths of all its members, signified by yeas and nays entered on the journal, that a bill or joint resolution is an emergency measure, it may proceed forthwith from second to third reading. No bill or joint resolution shall pass, unless there shall be a majority of all the members of each body personally present and agreeing thereto, and the yeas and nays of the members voting on such final passage shall be entered on the journal.
