A person who has obtained possession of property by theft or other illegal means shall be deemed to have a right of possession superior to that of a person who takes, obtains or withholds it from him by larcenous means.
A joint or common owner of property shall not be deemed to have a right of possession thereto superior to that of any other joint or common owner thereof.
In the absence of a specific agreement to the contrary, a person in lawful possession of property shall be deemed to have a right of possession superior to that of a person having only a security interest therein, even if legal title lies with the holder of the security interest pursuant to a conditional sale contract or other security agreement.
