On that special day in America when we celebrate all things macabre, take a look at a few stand-out tales involving spooky plaintiffs, scary defendants and Halloween-inspired litigation.

Banana Battle. Kmart is currently facing a lawsuit filed in New Jersey federal court last month over a full-body banana costume, which a New Jersey company alleges it owns the rights to. Rasta Imposta, which also names Sears Holdings Corp. as a defendant, asserts Kmart stopped buying its costumes and has since pilfered its Banana Design creation. (Costume at left isn't in dispute.)
