Again, is the information you received for an actual eviction or for charges for owed rent due to breaking your lease?
Your landlord provided you with a 5 day Pay or Quit notice. When you failed to remedy the situation (i.e., pay rent) within that time period, he then filed for the actual eviction. In the meantime, you moved out of the unit. It takes a while for the paperwork on filing for an eviction to go through the court system (i.e., setting up a date for the hearing).
When you go to court you argue why you believe you had the right to vacate the rental unit. If you don't attend the court hearing (assuming there is no need to since you've already vacated the rental unit), the landlord will be granted his request for the eviction. Such a judgement can allow him to further file against you for owed rent.
