The Herndon Town Council will meet in private Tuesday night to discuss changing the town’s controversial street solicitation law that opponents, who are threatening to sue over the law, claim violates immigrants' right of free speech and equal protection.

The law prohibits pedestrians from soliciting or selling merchandise or services to drivers on some public streets, effectively banning immigrant day laborers from gathering to seeking work.

The National Day Laborers Organizing Network and Advancement Project sent a letter to the Town Council in October outlining their concerns and have threatened to take Herndon to court.

Opponents were expected to present the council with a list of changes they want to see to the law Tuesday morning.
