HOA being strong armed by developer!!

There are 6 homes built in our sub division. That leaves the majority of the remaining lots under control of the developer. Every time we have a POA meeting and vote on something, he says that he has final say so because he owns the twenty some lots. Typically, he tables items in his favor. Most recently, he wants to increase sewer rates because he mismanaged our funds and now there is no money to fix our system. We have asked for accounting and tax documents from previous years and he still hasn't submitted them to us. He pays himself $100 monthly for administrative fees from our account! Not sure what that is for, as our sewer fees are direct deposited into his account. He even withdraws $200 yearly for tax preparation! He lives out of state and during a heated POA meeting, he said he would return the following month and purchase his air fee using our account! We are at our wits end and would like some advice. Thanks!
