The tactics of anti-immigrant group Border Watch, who are determined to keep undocumented workers from being hired, are well-known.

But a potential border backlash could end up in court. The question is whether immigrants would have a case.

It’s an on-going fight, pitting people who are looking for work against people who are looking to send them back home.

Now one side says it may be losing the battle.

Jose Luis Ramirez says he hasn’t found much work because US Border watch keeps interfering with his search.

It began months ago, when border watch volunteers started protesting in front of day labor sites And continued this past weekend in Spring, where volunteers not only targeted workers but people who hire them.

“Many of the workers feel that the presence of the Border Watch has scared some of the employers from coming to pick them up,” day laborer activist Maria Jimenez said.

So now they’re working on a new job: finding support to file a class action lawsuit against U.S. Border Watch.

“It is interfering with their right to work, and it’s interfering with the contractual right of parties to engage in a contract,” Jimenez said.

U.S. Border Watch readily admits taking pictures of contractors and their vehicles before warning them about hiring undocumented immigrants.

“We don’t do anything that’s in violation of any law,” Curtis Collier said. “Exposing someone for being illegally in our country is not a crime.”

But immigration experts said preventing people from getting a job could be a problem.

“If they are interfering with the right of these contractors to bring on contract laborers temporarily, I think they may have a basis for the lawsuit,” University of Houston immigration expert Joseph Vail said.

It’s a fight on the streets that could end up in court.
