The member who is reported to have bought the second car parking is playing fraud on the association as well as making fool of everyone for his wrongful gains.
Once the association has taken over the apartments, it becomes the absolute owner of all the common areas which includes the parking space.
The association can deny the car parking space claimed by the member for whatever reason he may cite.
Let him approach court of law and obtain an order, you can challenge the case as an association before court of law and get the case dismissed on merits and as per provisions of law
