Gay marriage proponents in New Jersey rallied on Sunday as New York's gay marriage law took effect.

Roughly 150 people looked on from the Pier A Park in Hoboken toward the Manhattan skyline as they rallied for marriage equality in the Garden State, the Hoboken Patch reported.

“New Jersey needs marriage equality,” Hoboken Mayor Dawn Zimmer told the crowd, “and we need it now.”

New Jersey is among the five states that recognize gay and lesbian couples with civil unions. In Hawaii, Illinois, Delaware and, most recently, Rhode Island lawmakers approved legislation legalizing civil unions. In New Jersey, however, civil unions were approved by the Legislature to remedy a state Supreme Court ruling declaring the state's ban on gay marriage unconstitutional.

Proponents attempted to legalize the institution last year during a lame-duck session of the Legislature before Governor Chris Christie, who opposes such unions, took office. The loss prompted supporters to return to court.

Sunday's rally was organized by gay rights groups Garden State Equality and Lambda Legal.

U.S. Senator Frank Lautenberg, Congressman Frank Pallone and state Senator Ray Lesniak spoke at the rally.

Lesniak said the Democratic Party in New Jersey is working on building a bipartisan veto-proof marriage equality majority in the Legislature before a new bill is introduced.

Middlesex County couple Marsha Shapiro and Louise Walpin, who are plaintiffs in the new lawsuit, told the crowd that “no one understands what a civil union is.”

“The time is now for us not to be treated as second class citizens,” Shapiro added.
