(Bloomberg) -- BNP Paribas SA won dismissal of a German suit by a trader seeking 163 million euros ($186 million) for a “fat-finger” mistake in a 2015 transaction.

The Frankfurt Regional Court on Feb. 26 rejected his case, which involved an error on the bank’s system that displayed derivatives for 108.80 euros instead of 54,400 euros each. Judges held he should have sued in France rather than Germany, a spokeswoman for the tribunal said on Thursday.

The trader, who can only be identified as Armin S., bought the securities over a platform that wasn’t covered by an agreement allowing investors to litigate in Frankfurt, she added. Armin S. has already filed a suit against BNP in a Paris court.

The German case is: LG Frankfurt am Main, 2-18 O 175/17.
