"Guilty" of Flying the Wrong Pattern?

From AvWeb:

"Larry S... was originally found guilty by an FAA administrative judge
of flying a right-hand pattern, in his personal aircraft, a Christavia,
at Chetek instead of the standard left-hand pattern. He appealed to the
National Transportation Safety Board and the charge was dismissed."

This struck me as a bit odd. He was "ratted-out" by another (I think)
non-FAA person who had a grudge against him. So can anyone report
things like wrong traffic patterns and/or pattern altitudes to the FAA
and get them to summon the pilot to a hearing of some sort?
