Problem: Supreme court:

When it comes to civil and criminal cases, the Bundesgerichtshof is at the top of the hierarchy of courts. The other branches of the German judicial system each have their own appellate systems, each topped by a high court; these are the Bundessozialgericht for matters of social security, the Bundesarbeitsgericht for employment and labour, the Bundesfinanzhof for taxation and financial issues, and the Bundesverwaltungsgericht for administrative law. The so-called Gemeinsamer Senat der Obersten Gerichtshofe (Joint Senate of the Supreme Courts) is not a supreme court in itself, but an ad-hoc body that is convened in only when one supreme court intends to diverge from another supreme court's legal opinion or when a certain case exceeds the authority of one court. As the courts have well-defined areas of responsibility, situations like these are rather rare and so, the Joint Senate gathers very infrequently, and only to consider matters which are mostly definitory.

Germany's Joint Senate of the Supreme Courts is also known by what name?

A: Gemeinsamer Senat der Obersten Gerichtshofe

Context and question: During the early 20th century it became increasingly common to bury cremated remains rather than coffins in the abbey. In 1905 the actor Sir Henry Irving was cremated and his ashes buried in Westminster Abbey, thereby becoming the first person ever to be cremated prior to interment at the abbey. The majority of interments at the Abbey are of cremated remains, but some burials still take place - Frances Challen, wife of the Rev Sebastian Charles, Canon of Westminster, was buried alongside her husband in the south choir aisle in 2014. Members of the Percy Family have a family vault, The Northumberland Vault, in St Nicholas's chapel within the abbey.
Who was buried in the south choir aisle in 2004?
Answer: unanswerable
