Traditionally, it has been left up to the attorney general to determine how and when to defend lawsuits challenging existing law. But there has been a growing trend for the executive branch to refuse to defend existing law against legal challenges.

Should the attorney general be required to actively defend existing laws both in the trial court and through the appellate process? Would such a rule be constitutional?
