ST. LOUIS (AP) — An eastern Missouri town faces a lawsuit over its fixed bail amounts that plaintiffs say violate the rights of the poor.

Velda City requires defendants to pay a set bail amount before being released on municipal court charges. The St. Louis Post-Dispatch reports the fee is $350 for driving with a suspended license and $150 for most other ordinance violations.

Two organizations, ArchCity Defenders and Equal Justice Under Law, filed the lawsuit in federal court, claiming the bail amounts are unconstitutional. They say the bail amounts don’t consider individualized factors and automatically lead to the detention of people who can’t afford to pay them.

The newspaper says the town’s municipal judge and city attorney couldn’t be reached for comment Tuesday.
