Okay there's a lot to unpack here and I'm assuming you're new to the field given the way you formed your question.

Are you asking about usecases for AI in government? If so there are many thousands of ways it could be used. From surveillance of cities for crimes, to tax fraud detection.

Are you asking about frameworks for determining if a particular usecase is ethical, fair, transparent etc.? There are many emerging frameworks around explainability, interpretability, fairness etc.

Are you asking how effective the frameworks for determining fairness, transparency, etc. are in evaluating each usecase? Well that's a much deeper question, and is still something everyone is exploring.
