Anything can be summoned

An African Gray parrot was summoned to court recently.

The dispute is over who is its real owner. The bird flew away from the home of one lady 3 years ago and landed at the home of another woman. The two ladies met by chance, and the first lady (the original owner) wanted the bird back. However, the second lady felt that the bird was too attached and shouldn't be returned. So, lady 1 filed a lawsuit, and the courts returned her bird.

It just goes to show, nothing is safe from a courts summons and you can file a lawsuit over ANYTHING.
