Association has decided to send him a Association notice to clarify the intention of flat usage - commerical or resident ? But question is how to send him a notice. As he removes a notice whenever placed on his flat's door.
The association should not be toothless on this subject. they have to decide about this by convening an emergency meeting to discuss about the issues to tackle this situation.
Is that legal to carry commercial activity inside residential apartment, if its not in interest of other residents ?
