The Washington, D.C. Council, the legislature for the United States capitol, unanimously passed an emergency bill to reform policing in the city.

The measure bans police from using chemicals such as tear gas and pepper spray on protestors, as well as “less-lethal projectiles” like rubber bullets and stun grenades. It also makes it unlawful for police to restrain someone by the neck, as in a chokehold. 

The bill also prevents the Metropolitan Police Department from hiring law enforcement officers who were fired from a policing job in another jurisdiction, or resigned ahead of pending disciplinary action or termination. 

Tuesday’s vote enacts the changes for 90 days, the Washington Post reported, which can be extended to 225 days with a second vote. The council must hold public hearings and vote again in order to make the measures permanent.

Councilmember David Grosso wanted an additional amendment capping the city’s police force at 3,500 members. However, Grosso’s fellow members voted that down. The District currently has 3,863 sworn officers.
