A question I didn't realize you have to go to law school to answer! (Although, you may need to be a philosopher).
Basically, a bakery shop owner in Massachusetts complained that his landlord violated a "sandwich exclusivity" clause by allowing a Mexican chain in the same shopping complex to serve...burritos. He didn't like the competition.
After consulting Webster's dictionary and speaking to expert chefs, the judge made this lofty ruling: "A sandwich is not commonly understood to include burritos, tacos, and quesadillas, which are typically made with a single tortilla and stuffed with a choice filling of meat, rice, and beans." To which I say, "NO DUH!!"
