Leakage from above flat in mumbai housing society

Hello, greetings of the day.
The Bye Laws clearly states that, the member renovating the bathroom should be permitted to conduct repairs against a prior written undertaking and can make a deposit of an amount refundable 3 months after the completion of leakage free repair as certified by the member occupying the flat below that flat on the immediately following lower floor. As per Bye Law No 159(b) all the repairs, that are not covered by the by law no 158(b shall be carried out by the Members at their cost. The expenditure of the internal leakage like due to toilet, sink etc. should be borne by concerned flat holders, with the intimation to the Society.
Hope this answers your query.
