My problem with this is that Lambert being banned and why he's been banned (not specifics mind) is public knowledge but the linesman, whilst not involved in games this weekend, appears to be serving an undefined demotion/suspension. There is nothing to suggest why (or even confirm that is the case, he could be missing for another reason), acknowledge the error, or suggest that it's something that shouldn't have happened.
The lack of clarity in officiating in football is one of the key reasons for the contempt they're held in, I mentioned it on the Dowd thread and Ozz mentions it here, being able to hear the comms between the officials (they're already using the equipment, it's just not made public) would serve 2 purposes.
1. there'd be an instant recognition of reasons for the decision.
2. the players could be picked up on it, hopefully stopping them surrounding the ref, etc.
