Speaking about the suspensions handed down to Alan Didak and Heath Shaw, Pert said misinformation was damaging to what clubs are trying to achieve.
"When you have two of your key players looking at the president, the coach and their own teammates in the eye and actually lying to them, it really destroys the essence of the club," Pert said.
"It was decided by the leadership group, the executive that these two players actually don't deserve to wear the Collingwood Football Club jumper and that's why they're not playing for the rest of the season.
"They have [explained why they lied] and we understand the reasons and we don't accept or support [it]," Pert said.
Chief of football operations Geoff Walsh indicated the decision from Heath Shaw and Didak to lie about the drink driving incident was not pre-planned.
"I don't think there was a defining moment that Heath said to Alan or vice versa: 'Hey, I'll say this' and the other one said: 'Yeah [I'll say this]'," Walsh said.
In regards to Collingwood president Eddie McGuire's "scaly mates" comments on Monday, where he referred to Heath Shaw's car passenger not realising it was Alan Didak at the time, Pert conceded those comments now sound "ridiculous".
"We've been put in that place by the two players because of the fact that they lied to us, so is it embarrassing? It's unbelievably embarrassing to someone like Eddie McGuire," Pert said.
"When you look at all of the things that we said by Scotty [Burns] and Eddie – in hindsight they probably look silly – [but] based on the information, I was very comfortable on how we dealt with it [at the time]."
