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.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What court sits in supremacy for cases related to employment and labor law in Germany?
Ah, so.. Bundesarbeitsgericht

As a result, in 1979, Sony and Philips set up a joint task force of engineers to design a new digital audio disc. Led by engineers Kees Schouhamer Immink and Toshitada Doi, the research pushed forward laser and optical disc technology. After a year of experimentation and discussion, the task force produced the Red Book CD-DA standard. First published in 1980, the standard was formally adopted by the IEC as an international standard in 1987, with various amendments becoming part of the standard in 1996.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What did the team create five years after joining?
Ah, so.. unanswerable

China: The torch returned to China for the first time since April. The torch arrived in Sanya, Hainan on May 4 with celebrations attended by International Olympic Committee (IOC) officials and Chinese big names like Jackie Chan. The entire relay through Mainland China was largely a success with many people welcoming the arrival of the torch along the way.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): After its April departure, when did the torch return to China?
Ah, so..
May 4
