DENVER (AP) -- A special session to consider civil unions for same-sex couples will start Monday.

A spokesman for Democratic Gov. John Hickenlooper said more details about the upcoming session would be announced later Thursday.

Hickenlooper announced his plan to call for a special session on Wednesday -- the final day of the regular session -- after the civil unions measure failed without a vote in a late-night standoff in the Republican House.

Hickenlooper supports civil unions legislation and says the proposal deserves a vote by the full House.

This will be the Legislature's first special session since 2006, when they were called to Denver to consider immigration bills.
