"We were surprised but if that's what it is now, then that's what it is," coach Laurie Daley said. "We thought that would have been an offence but obviously it's not.
"Obviously the match review panel thought it was accidental. If it was accidental I don't know why you'd be jumping up and going '1-all'."
Added Pearce: "That's just how it is. If we do the same thing in game three it's play on."
Asked about the prospect of a free-for-all at ANZ Stadium on July 17, Pearce said: "I don't think it will - probably the first guy that does that will get binned.
"That's just how it is now. It's a shemozzle."
The Maroons were just as upset at what they thought was an unprovoked attack by Merrin on Tate.
Tate pushed Paul Gallen to the turf in the play the ball, Merrin reacting before a number of players joined in, with Greg Bird and Justin Hodges being sinbinned along with Merrin and Tate.
Merrin could be in line for some more punishment next time out against the Maroons.
"I think Merrin got a week for a king hit so that sets a precedent doesn't it," Maroons star Johnathan Thurston said.
"Tatey was looking down and copped a couple on the chin. The judiciary's dealt with it but he deserved more than a week, yes."
