Can my high school administrator tow my car?

we had a go green assembly yesterday and i left school with my friends and when i got in my car my administrator walked up and asked if i had a pass to leave, i said no and he said to park and get out so i backed up and turned it off and pretended to get some books together while he went to the kid in the car next to me, i then turned my car back on and peeled out of the parking lot while he was just starin at me leavin, the next day i was given a pass to go to the office and i didnt go, then he personally came and got me in my 5th class and told me i am no longer allowed to park my car there, im just wondering what he can actually do if i just park there, can he have me towed or give me a ticket or anything like that? nby the way i paid 10 bucks like everyone else at the beginning of the year to get a tag that lets me park for the entire year, and theres no contract or any warning that says i can lose that priveledge
