I don't know much about German law citations, but I guess that I already can say, that I don't like it. I found: http://www.niederle-media.de/Zitieren.pdf and on page 27 there are some examples how to make a short citation (in the footnote) for a case. It will not be present in the bibliography. In the example here I guess one would cite it as "LG Augsburg: BKR 2001, 99" or with any of the other parallel publications (see extra). If you are more sloppy, you may also ommit the court, i.e. "BKR 2001, 99" (shortTitle).
