Is there a difference between the words "of'' and "after?'' A federal court says no, at least not in a dispute between a Detroit man and a debt collector.
 
Carl Wallace sued Diversified Consultants. He accused the company of violating a federal law because of the wording of a debt notice related to a $2,000 phone bill.
 
Wallace was asked to respond within 30 days "of'' receiving a notice. But the law covering debt collections says people have 30 days to respond "after'' getting a notice.
 
So what? Indeed, that's what an appeals court said Wednesday in affirming the dismissal of a class-action lawsuit in Detroit federal court. The court doubts that anyone who got the letter was confused.
 
Attorney Brian Parker of Bingham Farms was seeking thousands of dollars.
