Father aged 70 years recently expired due to Cardiac arrest, he was fighting a case with Karnataka municipal corporation for Violation of Building setback area for 5 years now. On his demise, the Govt officials came on the same day with an order stating that Karnataka Appellate Tribunal: Stay got vacated and they wanted to demolish the building. We are already in a state of shock with sudden demise of father and the Govt officials without letting us any time to understand the alternate ways are harassing us. Mother is in a state of depression and we are trying to bring her back to normal. Is there any provision in Karnataka Municipal law, a. After demise of the owner, the Legal heirs should be intimated with notice period allowing them to respond to the Govt Orders. b. The Govt officials acting inhuman, not allowing the family to follow the Hindu rituals on fathers demise, we do not make any changes or discuss about development until the 40th day from his demise. Any provision in the Human Rights policy. c. In general, how many days time can the Court allow the family
