Regarding parking my car beside my corner house

I live in a society and I have a corner house. Right side of my house is at corner. I have been facing a problem for months done by known people/neighbours around the corner of my house. The society secretary has decided to park vehicle on a corner of every house at price of 300rs per car, when i have buy my house there were no such rules, after 2 months from i buy house, the people who have car have gathered and make the rule for parking car at 300 rs per month on the corner place, i have 2 car and when i buy that house the previous house owner had said me that you can park your car tn corner side of your house because when earlier police had came on this matter, they had said thay the first right is of corner house owner to park their vehicle, but nobody has listened, the people who are parking are saying that this is society common plot and parking their vehicle, i had pay more for corner house for park my vehicle and after this all happened i am very tensed for parking my vehicle, Their vehicles are always parked at the corner of my house, 24/7. I am not able to park my own car there. I want them to leave the corner area of my house for my own use. What should I do?
