The City Council took action to join a lawsuit attempting to block the Bowery Residents Committee homeless shelter in Chelsea yesterday, as the facility began moving people in.

The council’s General Welfare Committee voted to allow the legislative body to join the lawsuit against the city filed by the Chelsea Flatiron Coalition, a group of residents, businesses and property owners.

Opponents argue the 328-bed facility breaks the city’s law limiting homeless shelters to 200 beds.

The full council plans to vote today to permit the body to join the lawsuit.
