"We have decided not to refer it to the judicial officer for a breach of conduct hearing, given Lam's willingness to make both a public and private apology about the matter.
"But this should serve as a reminder to everyone that comments will be treated very seriously and there needs to be a threshold.
"This is about calling into question the integrity of people in the game. It is okay to say something like a decision was tough but to go to the next stage ... brings problems."

Lam acknowledged the need for interaction with the media and the public but said there were times when certain issues were best left for more direct dialogue between Sanzar and franchise officials.
