In most states, an attorney general’s power and authority come from the common law (custom and judicial precedent) rather than statutes. Under common law precedent, attorneys general have the authority to represent, defend, and enforce the legal interests of both the state itself and of the public. The jurisdiction’s constitution and statutes also establish the attorney general’s authority in other areas.

Depending on the decisions of the state's courts, attorneys general may have common law authority to:

  • Protect the public interest. 
  • Control litigation and appeals on behalf of the state or territory.
  • Appear for and defend the state or territory and its agencies. 
  • Determine the legal policy of the state or territory. 
  • Intervene in legal proceedings on behalf of the public interest. 
  • Prosecute criminal activity (in the absence of express legislative restrictions). 
  • Seek abatement of a public nuisance. 
  • Seek writs of prohibition against judicial actions. 
  • Enforce charitable trusts.
