The CLA exists to maintain and promote the rule of law throughout the Commonwealth. One way in which the CLA achieves this objective is to monitor respect for the rule of law in Commonwealth countries and take appropriate action if there are concerns or where there has been a breach. The CLA's response can be in the form of a public statement, intervention via letter to the appropriate authorities, submission of an Amicus brief or Opinion, or working behind scenes with the relevant parties to bring about an acceptable resolution of the situation.

At every stage, the CLA works closely with the local law society and bar association to support the local profession in their own efforts to maintain the rule of law.
