Related to document review is policy analysis. Policy commitments, contents and interpretations, and processes can all be examined.
Studying changes in policy over time can identify laws that successfully protect and fulfill human rights, as well as laws that are harmful.
The existence and implementation of policies on a particular subject can be examined with respect to international human rights norms and commitments.
Policies can also be compared across states and mapped against different effects and outcomes.
The UN Treaty database is one starting point for state obligations. Comparative databases like the Global Gender Equality Constitutional Database also facilitate tracking of government commitments.
