Given that you are on the EC, the fact that he is an office- bearer affords him no greater rights than you or the other members of the committee.
Some options to consider:
1)Issue a notice to comply regarding noise and common property.
2)Take him to the CTTT (you personally or the OC)
3)Get the numbers together and vote him off the EC
4)Repeat steps 1-2 as necessary (and it sounds like it will need repeating with this chap) until you get satisfaction
Good luck
