Excuse me if this has happened before but I dont recall it every happening.

(Firstly I would like to say I disagree with this anyway and in the event of a 2-2 tie it should go back to the public vote but no matter that is academic.)

Do you really think Len would in the event of it being 2-1 use his casting vote to decide the result.

Ohh Yeah

it happened this year when Don and Lilia were in the dance off for the first time. Didn't Len use his casting vote to save them.
