A group of district judges in Houston on Thursday argued for dismissal of a lawsuit alleging their felony bail practices are unconstitutional because they discriminate against poor people, keeping them jailed when they can’t pay bail.

Among the defendants are the 23 criminal district judges of Harris County. Now, 20 of them argue that the plaintiffs lack standing, and the judges have immunity to the claims. These 20 defendants say the plaintiffs were all released on bail and they don’t have an injury that qualifies them to sue.
