"We could not win that game, no matter how well we played," was Levein's assessment to Setanta Sports.
"I think Mike McCurry is one of the more ballsy referees and will give decisions, but today he didn't.
"They were absolutely ridiculous decisions, there were no doubts."
Commenting on Weir's challenge on Hunt, Levein added: "It is a red card. The rules are that if you are through on goal and preventing a goalscoring opportunity, I don't know what is. He is inside the box in front of goal, it's a sending off."
Reflecting on Swanson's disallowed strike, Levein added: "It hit Davie Weir. The linesman started off saying it hit Robertson and then all of a sudden they worked out it hit Weir and they say Robertson ran across the keeper, 20 yards from goal. It is ridiculous."
