The Uruguayan was suspended for 10 matches for biting the arm of Chelsea’s Branislav Ivanovic on Sunday with the severity of the sanction surprising Rodgers.
The Reds boss feels that there was way too much outside influence over the decision and has called for a clear-cut disciplinary protocol to be adhered to in future.
"We need to understand what an independent panel is," said Rodgers. "We had been given clear indications by the FA that there was going to be an independent - or so-called independent - case put together and then we would receive what that sanction would be.
"If you are an independent panel and yet the day beforehand the FA come out and say Suarez will serve more than three games it is not independent because they are already putting pressure on the sanction.
"There is a prejudice there straightaway.
"But when you look at it in the cold light of day then it was violent conduct. It is the first time I have ever heard of an independent inquiry being dictated to by so many people.
"There is absolutely no doubt there should be a protocol in place which tells us what the variances are because there are inconsistencies there."
