Brighton manager Gus Poyet believed referee Andy Haines had been influenced by the home crowd during the Seagulls' 2-1 defeat at Huddersfield.
Town skipper Peter Clarke brought down Glenn Murray in the penalty area in the first half, with Poyet making a 'red card' gesture to the fourth official and ref Haines.
Poyet said: "The noise of this stadium got into the head of the referee. He started making decisions as if it was Manchester United playing at Old Trafford."
Clarke was only shown a yellow card and Murray missed the spot-kick but made amends by toe-poking the visitors into the lead midway through the second half. The lead barely lasted two minutes, though, as Jordan Rhodes levelled before Jamie McCombe grabbed the winner late on.
The Uruguayan insisted Clarke deserved a red card when conceding the penalty.
He added: "If you're honest you know it's a red card. Even if I was playing and it was given against me I would still have been honest and said it was a red card.
"If we'd have had another referee then perhaps we might have won the game. I thought we created the best chances and played really well. I can't fault my players for the effort."
