Does the Attorney General have power to amend the law or enact additional laws for the public good?

The Attorney General also relies on Doe v. Harris (2013) 57 Cal.4th 64 (Doe) for his contention that plea agreements are deemed to incorporate the reserve power of the state to amend the law or enact additional laws for the public good. (Id. at p. 71.) In Doe, the court held that requiring a sex offender to comply with retroactive postconviction amendments to California's Sex Offender Registration Act section 290 et seq. did not violate his plea agreement. (Doe, at p. 73.)
