House Democrats, led by the Congressional Hispanic Caucus, used some procedural creativity Thursday in filing a resolution to discharge a bill that could ultimately lead to a vote on the so-called DREAM Act.

The DREAM Act is a measure that Democrats and some Republicans want to pass as a legislative solution to President Donald Trump’s decision to end the Obama-era Deferred Action for Childhood Arrivals program, or DACA, that sheltered roughly 800,000 undocumented immigrants who came to the United States as children from deportation.

The measure would provide certain conditions under which those covered by DACA can obtain permanent legal residential status and eventually even citizenship.

A discharge petition is a procedural tool under which members can try to bring a bill to the floor against leadership’s wishes. The tool is most often used by the minority party and it requires the signature of a majority of members to discharge a measure to the floor, so most discharge efforts are not successful.

The problem Democrats encountered in wanting to file a discharge petition on the DREAM Act is that House rules require a bill to have been introduced for 30 legislative days, or days in session, before a resolution to discharge can be filed.
