The Rugby Football Union is to take no further action against Harlequins or any of the club's staff or members in the wake of the fake blood scandal.
The RFU's disciplinary officer Jeff Blackett says the bans and fines already issued are sufficient punishment and there is insufficient evidence to support a case of misconduct which has not already been considered by Heineken Cup officials.
He says there will, therefore, be no further misconduct proceedings against Harlequins in relation to the use of fake blood, or any related activities up to the final European Rugby Cup appeal hearing.
The ERC said earlier this week it would be taking no further action against the club following the use of a fake blood capsule by winger Tom Williams to facilitate a blood replacement substitution during a Heineken Cup game against Leinster last season.
Blackett said it was not in the interests of the RFU or the game to investigate the matter any further.
