Leicester Tigers have strongly criticised the Rugby Football Union over its handling of Richard Cockerill's ban.
Cockerill, Director of Rugby, was banned for nine matches for his conduct towards fourth official Stuart Terheege during Leicester's Aviva Premiership final victory over Northampton.
Leicester will wait to receive a copy of the full written judgement before deciding whether to appeal the verdict but they are angry with the RFU's role in the case.
A club statement said: "There are elements of the way in which they have conducted this case which, in our opinion, calls into question the new disciplinary structure and we will be taking this up with the RFU at the earliest opportunity."
Northampton Saints and England hooker Dylan Hartley has been banned for eight weeks for biting an opponent.
The RFU found him guilty of biting Ireland's Stephen Ferris during a Six Nations game earlier in March 2012.
The ban means he will be available for England's summer tour of South Africa, but will only play for Saints again this season if they reach the Aviva Premiership final.
