Head coach Andy Robinson was unhappy with the refereeing of Nigel Owens as Scotland fell to a 21-18 RBS 6 Nations loss to Ireland at Murrayfield.
Robinson highlighted the 13-4 penalty count against Ireland and the sin-binning of Allan Jacobsen after half-time as key to his team's defeat.
The Scotland head coach, who will attempt to speak to Owens about the decisions, said: "There are a number of issues that I have about the game."
He added: "Firstly, the high Irish penalty count and no sin-bins and their ability to slow our ball down illegally.
"Secondly, I thought the scrums just after half-time - when we've got the Irish going backwards and there was a penalty against us and then from the next scrum our prop (Jacobsen) was sin-binned - was a major turning point in the game.
"We were just about to get on top of the Irish and to lose a player like that is pretty hard to come back from.
"But I'm delighted with the way the team came back from that.
"I want to know why he made those calls."
