Finally I found something with some legal "teeth." I wish I could find a way to cut and paste it here, unfortunaly I am not computer literate enough. It is NTSB Order EA-4236, dated August 22, 1994.
Here's the story a 21,000 hour Chief Flight Instructor did not believe that straight-in approaches were legal, Doing pattern work in New Jersey he cut-in front of somebody that was making a straight-in. In the end the NTSB sided with the FAA and REVOKED all of his certificates for failure to give right of way 91.113 and for endangering 91.13 the people making the staight-ins.
Let that be a lesson to all the traffic pattern "nazi's" out there! Bottom line though, everybody still needs to cooperate!
