A more thorough explanation:

The Court of Exchequer Chamber was an informal gathering of common-law judges who met to discuss important cases that had adjourned pending an opinion from the Court. Although it was never officially recognized as a court of law, the judges gave great weight to its decisions. The last reported decision of this body is from 1738.

For example, if a case was too difficult for a lower court to decide, it could be referred to the Court of Exchequer Chamber for further discussion and opinion. The judges would then gather to discuss the case and provide their opinions, which would be taken into consideration when making a final decision.

The Court of Exchequer Chamber played an important role in the English legal system, as it helped to ensure that difficult cases were given the attention they deserved and that the final decision was based on the opinions of experienced judges.
