New York state’s Office of Court Administration issued updated rules Wednesday that immigration advocates hailed as a check on the ability for Immigration and Customs Enforcement agents to make arrests inside state courthouses, just a week after a new, 80-page report detailed the impact of federal immigration officials operating in the state courthouses.

“We have concluded that this report provides us with a sufficient basis to take the step that many have asked us to take to require that ICE present a judge-issued warrant before conducting an arrest in a state courthouse,” Chief Administrative Judge Lawrence Marks told the New York Law Journal. “Although we’re not aware that any other court system in the country has taken this step, this comprehensive, well-documented report has convinced us that this change in policy is now appropriate and warranted.”
