Society audit

I have couple of questions on Society Audit:

1. In a housing society (registered under karnataka Societies Registration Act, 1960), who all is required to sign on a resolution passed in a general meeting. Would it suffice if just president and secretary sign the resolution?

2. What is the consequence if Audited financials are not passed/approved in an AGM? Can it be approved by calling a special general meeting?

Thanks in advance.
