James Parkes came on as a second-half substitute during the game resulting in a loss of two points. Leicester were only docked one point for the same offence and after seeking legal advice Saracens decided to contest the decision.
An independent Appeals Panel will be appointed by the Rugby Football Union to hear the case in accordance with the competition regulations of the Premiership.
"The RFU acknowledges that this is a very important case which will be chaired by the RFU Disciplinary Officer, Jeff Blackett," said RFU disciplinary administrator Bruce Reece-Russel.
Saracens, meanwhile, do not feel they were treated unfairly, but rather that the law should not feature in the professional game. There are also fears the penalty could come back to haunt the club at a later stage.
"We're not trying to suggest that we've had an unfair hearing," said Saracens CEO Mark Sinderberry, "it's more about the fundamental issue that the law was designed for the amateur rather than the professional game.
"Penalties in professional sport, as in the commercial world, need to be appropriate and quantifiable. Right now as it stands we don't know how it will effect us. Maybe come the end of the season it will make no difference but then again it could cost us a Heineken Cup spot, a place in the Zurich Premiership Semi Finals or Zurich Wildcard Play Offs or worse still be relegated, we just don't know.
The appeal is set to be heard in December this year.
