Huth's suspension for violent conduct was imposed after he caught Fulham's Philippe Senderos in the face with his arm at Craven Cottage.
Kemp was already upset by that decision, but he says the sense of injustice has been heightened by Wigan's Callum McManaman escaping punishment for his horror tackle on Newcastle's Massadio Haidara.
The Football Association said one of the match officials saw the McManaman incident but did not take action at the time, so no retrospective action was possible.
"It's fantastic to have Huthy back and available again," Kemp told The Sentinel.
"Seeing him miss three games for a flailing arm - and then seeing nothing for what happened with the Wigan player - it adds to the injustice of it all.
"Everybody has different make-ups and he's a big lad who has to keep on top of his fitness, but he will have been looking after himself and getting himself ready.
"Marc Wilson has performed well at centre-half in his absence, but you always miss a player of Robert's quality and stature."
