Special courts are also known as Article III courts.

Explanation:

The Article III of the United States Constitution provides for the establishment of courts that serve special and temporary purposes. These include the courts like fast-track courts, tribunals, appellate courts, etc. When a matter is to be heard and given a decision on urgently, it is presented in front of a specially formed fast-track court. For matters that require special conscience and expertise, tribunals are established with expert judges.
