A proposed constitutional ban on same-sex marriage was swiftly defeated today by a joint session of the Legislature by a vote of 45 to 151, eliminating any chance of getting it on the ballot in November 2008. The measure needed at least 50 votes to advance.

The vote came without debate after House Speaker Salvatore F. DiMasi, Senate President Therese Murray, and Governor Deval Patrick conferred this morning and concluded that they have the votes to kill the proposal.

"Today's vote was not just a victory for marriage equality, it was a victory for equality itself," Patrick told reporters as cheers echoed in the State House. "Whenever we affirm the equality of anyone, we affirm the equality of everyone."
