Unapproved major reno. Help me compose motion for agenda.

First time committee member and first time user here. 

Please help me to reply to my strata managing agent and to compose a motion for our general meeting regarding unapproved major reno that an owner has undertaken.

The agent email me to ask for a wording of motion for the general meeting, including raising ~4000$ for lawyer fees. He wants me to set the due date in which the levy to be paid to pay this fees.

Question:
1. I don’t believe the Owner corporation (eg the rest of us have to pay for lawyer cost). How can I best answer his email without putting myself liable for any damage/cost that will be incurred by owner corporation? Anybody have sample of meeting motion to bring up unapproved works in meeting?

2. What happen if – there is no other owner attends the meeting and that there is still no approval for unit 1 renovation being sought by Owner of Unit 1?  I have written request for owner Unit 1 one to provide details of work (major bathroom renovation), however it has been ignored. Due to lack of action from agent, I believe the renovation of Unit 1 is now completed. We don’t know what exactly is he doing! Can I go ahead to appoint a lawyer?

3. Would I be able to apply to tribunal for a dysfunctional strata if no other owner is responding / strata manager is still not helping out?

Thanks in advance guys. Really appreciated as this matter has been doing my head for the past months :-  My agent does nothing and putting responsibilities and blame toward me as the only committee member (out of 4 unit). Other owners are inactive.
