The building is within Municipal corporation. Ground floor has many shops. The building has around 10 to 15 ft wide and 1000 ft long open space. One of the shop owner is carrying out plumbing work with heavy machinery in front of his shop occupying the society owned common area claiming that area in front of a shop belongs to the shop owner. Not allowing people to walk through and go to other shops. Is this encroachment?? If so how can it be challenged?? Whom to approach??? Can there be a permanent solution?? No one opposing The shop owner being of criminal background. Awaiting for a proper guidance for a legal action.
