Faithful Execution of the Law Act of 2023 This bill expands the circumstances under which the Department of Justice (DOJ) is required to report to Congress on a policy to refrain from enforcing federal law. Currently, DOJ is required to report to Congress when the Attorney General or other DOJ officer establishes or implements a non-enforcement policy on the grounds that the relevant provision of law is unconstitutional. This bill requires DOJ to report to Congress when any federal officer establishes or implements a non-enforcement policy on any grounds. Further, the bill requires the report to state the grounds for the non-enforcement policy.
