Answer:
Due to its failure in drafting a new constitution, the CA was dissolved on May 28, 2012 after its original and extended total tenure of four years. The next Nepalese Constituent Assembly elections initially slated for November 22, 2012 were held a year later on November 19, 2013 after being postponed several times.
Supreme Court is the correct answer.
Article III of the Constitution established the Judiciary, including the Supreme Court and any other lower courts that would be later established by Congress.
However, there is no mention of the Circuit Court system or any of the myriad of other courts now in existence.
