This exact case had been discussed on the blog on the past. The ordinance would have required apartment managers to verify that renters are U.S. citizens or legal immigrants before leasing to them, with a few exceptions.
Landlords would have faced fines of up to $500 for violating the measure with each day considered as a separate violation.
U.S. District Judge Sam Lindsay, who stopped the enforcement of the ban was appointed in 1998 by President Bill Clinton.
Before I researched Judge Lindsay, I figured him to be a liberal Democrat, as he indeed is.
On a personal note: If the Democrats take the White House in 2008, we will see a great deal more of these kind of ruling. If it happens, God help us!
