Consider the following statements: 1. The Commonwealth has no charter, treaty or constitution 2. All the territories/countries once under the British empire (jurisdiction/rule/mandate) automatically joined the Commonwealth as its members. Which of the statement given above is/are correct?

Both statements are incorrect. The Commonwealth has an official Charter (adopted in 2013) and other intergovernmental instruments that define shared principles and commitments, so it is not true that it has no charter or founding text [1]. Membership is not automatic for all former British territories; the modern Commonwealth was reshaped by the 1949 London Declaration and operates as a voluntary association where states join by agreement and application rather than by automatic entitlement. Moreover, some members (e.g., Mozambique and Rwanda) have never been British colonies, demonstrating that historical British rule is neither a necessary nor sufficient condition for membership [2].
