What are a holdover tenant's rights in a retaliatory eviction?

Question Details:

I gave a 60 day notice of intention to vacate my apartment, unfortunately, I had to stay an extra month and a half. 1 month after my lease expired, I was served a summons for eviction for staying beyond my lease term. Was I supposed to get any type of Notice to Quit? Can the Landlord legally raise my rent after holding over by more than 50% without giving me any notice? And finally, can the landlord seek payment of this premium of more than 50%, whereby I am taking this matter to court, and threaten me to pay up, or my account will be sent to a collections agency?
