A Royal College in some Commonwealth countries is technically a college which has received royal patronage and permission to use the prefix Royal. Permission is usually granted through a Royal Charter. The charter normally confers a constitution with perpetual succession and the right to sue or be sued independently of the members. The charter also usually provide for rights of recourse to the Queen in Council. Although incorporation is now cheaply and easily obtainable by registration, the distinction of a Royal Charter means that such charters are still sought by and granted to institutions considered to be in the public interest, typically learned professional societies.
