A bill to scrap New York’s antiquated state law banning adultery now heads to Gov. Kathy Hochul’s desk after being approved by legislators.

The measure sailed through the state Senate 57-4 Wednesday without any debate on the Senate floor.

“We’re down to 9 commandments!” one lobbyist outside the Senate chamber said with a chuckle.

The current law, written in 1907, dictates that someone found guilty of adultery can be sentenced up to 90 days in prison or face a $500 fine. 

“I think it’s just kind of an antiquated law that was not really in practice in New York state so we’re just updating it and that’s always important to do whenever we have the chance,” state Sen. Jessica Sparcella-Spanton (D-Staten Island) said leaving the chamber after the vote.

The state Assembly passed the measure last month, meaning it just needs the swipe of Hochul’s pen before New Yorkers can have that fling without fear of ending up behind bars.

“Governor Hochul will review the legislation,” a spokesperson for the governor wrote in a statement to the Post.
