Inter se

Inter se is a Legal Latin phrase that means "[a]mong or between themselves". The phrase is "used to distinguish rights or duties between two or more parties from their rights or duties to others." For example, "The constitutional documents of a company constitute a contract between the company and its shareholders, and between the shareholders inter se." In Australian constitutional law, it refers to matters concerning a dispute between the Australian Commonwealth and one or more of the Australian federal states concerning the extents of their respective powers.
