Livingston manager David Martindale: "The contact's initiated by the Dundee player. At the time, in real time, I thought it looked like a pen, but I watched it back and I go, 'there's no chance that's a pen'.
"The VAR officials then send a referee to the monitor, which tells me there's two people looking at footage with different camera angles, saying, 'you might have made a mistake here, I think you'd better go and look at the monitor'.
"He looks at the monitor and then says, no, it's a pen. I said to the referee after the game, 'you'd better hope you've got that right'.
"This can't keep happening. It can't. It's me that's affected this week, it'll be somebody else next week. Rangers, Kilmarnock, Celtic benefit, Hearts benefit, it can't keep happening.
"We're paying millions of pounds for people to make decisions using footage. They seem to still be getting it wrong.
