Advocacy groups sued the Trump administration on Tuesday in an effort to block a rule published last month that expands the number of migrants who can be subject to a sped-up deportation process without oversight by an immigration judge.

The rule, published in the Federal Register on July 23, broadened the practice of “expedited removal” to apply to anyone arrested anywhere nationwide who entered the United States illegally and cannot prove they have lived continuously in the country for at least two years.

Previously, only migrants caught within 100 miles of a U.S. border and who had been in the country for 14 days or less were subject to the fast-track process.

Under expedited removal, migrants are not entitled to a review of their cases in front of an immigration judge or access to an attorney.

The lawsuit, filed in U.S. District Court in Washington, D.C., by the American Civil Liberties Union and the American Immigration Council on behalf of three immigration rights groups, claims the government did not go through the proper procedures in issuing the rule and says it violates due process and U.S. immigration laws.
