Neighbor nuisance

I am a BSc graduated cerebral palsy case from Mysore, Karnataka. My neighbor has planted a coconut tree out side of his compound wall, which has bent towards our gate. I asked him to cut off the tree and he did not oblige. He told me that, he has watered it for so many years and he need it. All coconuts fall on our side of the gate, while plucking. In addition to this, he has put a bunch of plants on his side of our wall. When I asked him to remove them, plaster the area with cement too, he did not oblige. Presently he has constructed villa upstairs too. While constructing upper villa, he has put a water tank in such a way that excess water while pumping up the water, will fall on our entrance, in such a way that, the person standing waiting for people to open the door will have a nice holy bath! Addition to this, he has put up a tiled roof for his upper portion of the roofing such a way that, the water falls on our car shed and also on our side of car parking area. He has put up a sheet for showing that the water does not fall on our side. But, It falls. I gave a police complaint for which he silenced them through his wife's brother who is in the same department. I even tried giving complaints to MUDA and also in the City Corporation. But, they kept quite by giving lame excuses because of his political backing. Now, what can I do for these problems ?
