Scenario:A homeowner planted a tree in the backyard. For twenty years the tree grew and grew, to the point that its branches eventually extended over the property of a neighbor. During this time, the homeowner made no attempt to cut back the branches of the tree. As a result, each fall, the branches deposited large amounts of leaves on the neighbor's property and, as the tree was quite tall, the branches blocked the TV satellite dish on the roof of the neighbor's home, resulting in interference in the TV reception. Is this trespass?

What is the basis of any legal action the neighbor has against the homeowner?What would/could be the homeowner's defense(s) ?
