Answer: Acting as a Supreme Court
Explanation:
You did not mention the relevant assembly however the above should be correct.
Assemblies usually belong to the Legislative arm of Government which means that they pass laws and in certain countries run the army and even choose the generals or admirals in the nation's forces.
