Is it legal to tow car if the reason given was all four tires were parked in the grass?

My car was towed from my apartment complex at 2:35 a.m. The car was parked in a patch of dirt and on broken pavement. My car was towed 5 days after I filed an answer to a summary ejectment for in NC for retaliatory eviction. My neighbor’s car was unregistered, however his car was tagged with a sticker, I was not afforded the same opportunity. I asked for a probable cause hearing because the towing company notified me through the DMV, that they had my car, however when we got to Court, the tow tickets states the car was towed at the request of management at 2:00 a.m. The tow company signed an agreement with the management company to tow illegally parked cars on the 6th of December to begin on the 20th of January. They just happened through and towed the car at 2:00 for being parked in a patch of dirt. I need some help.
