Wal-Mart Stores Inc. is asking a state court in Michigan to dismiss a lawsuit by former marketing executive Julie Roehm over her firing, arguing that Roehm should have filed the case in Arkansas, where she lives and where Wal-Mart is headquartered.

Wal-Mart spokesman John Simley said Friday that Wal-Mart filed the motion last week after a federal judge in Michigan declined to take over the civil lawsuit and sent it back to a state trial court there.
