Legal Definition
Where a suit is instituted on behalf of the crowu or government, or of those of whom it has the custody by virtue of its prerogative, or whose rights are under its particular protection, the matter of complaint is offered to the court by way of information by the aitomey or solicitor general, instead of by petition. Where a suit immediately concerns the crown or government alone, the proceeding is purely by way of information, but, where it does not do so immediately, a relator is appointed, who is answerable for costs, etc., and, if he is interested in the matter in connection with the crown or government, the proceeding is by information and bill. Informations differ from bills in little more than name and form, and the same rules are substantially applicable to both. See Story, Eq. PI. 5; 1 Daniell, Ch. Pr. 2, 8, 288 ; 3 Bl. Comm, 261.
