Corpus fund from new owners amended to bye-laws without registrar approval

Hello Everyone I recently purchased a flat in Bangalore 8 months back. The owner's association is asking me to pay a corpus fund of 60,000 rupees even though my previous owner had already paid the corpus fund. When questioned, they say the law has been passed from 2018 and all the new owners have paid until date. This is the law they passed in the 2018 AGM meeting: "The AMC proposed to collect a Corpus Fund of 60,000 rupees from the new owners to become a member of the association". My concerns: 1. Is it legal to collect corpus fund from new owner even after the old owner has paid it? 2. Do we need to pay additional amount to become a member of the owner's association? Shouldn't it be by default? 3. If the law was amended to the byelaws, should it be approved by the registrar to be abided? Or should we abide even without the registar approval in this case? 4. They threatened to stop my facilities if I don't pay the corpus fund, even though I have been paying a maintenance of 7000 rupees every month. And they cut off my power supply for 4 hours. Please suggest how I should deal with this matter? I am a single woman staying with my mother in the apartment. Thanks in advance.
