The Braunschweig District Court said in a statement (link in German) that it had registered 170 lawsuits against Volkswagen from mostly private investors. unit complaint was signed by 277 investors from both Germany and abroad, it said.

The court will employ Germany’s capital markets law on misrepresentation of capital market data, and attempt a single case which will then be applied to entire similar cases, it said.

vehicle manufacturers in Germany will now be required to build disclosures of their engine software to regulators below plans announced by the nation’s transport minister in December.

The disclosure of engine software will be required as portion of a recent “authorisation procedure” vehicle manufacturers will desire to engage with in Germany, the Federal Ministry of Transport and Digital Infrastructure told in a statement.

In June, Germany called on the EU to improve rules on vehicle emission testing to cover the range of adaptations to emissions control systems used by vehicle manufacturers.

While no other manufacturer was using a similar system to Volkswagen’s, “it became clear that for multitudinous vehicle types, real driving emissions are significantly higher than on the dynamometer”, Germany told the European Transport Council.

Manufacturers adapt emissions control systems to driving and environmental conditions in diverse ways, but primarily based on a temperature window outside of which the emissions reduction is reduced. This is allowed legally if it is done to protect the engine, but there are doubts over whether this is the case for entire the vehicles, and legislation is being interpreted in diverse ways, the note said.

Legislation should therefore state that defeat devices may only be used if they are needed to protect the engine even when using “the best available technology”, according to the note.
