Delaware court upholds dismissal of GM shareholder suit

Delaware's Supreme Court has upheld the dismissal of a lawsuit filed by General Motors shareholders over faulty ignition switches.
After hearing arguments this week, the court affirmed a judge's ruling from last summer.
The judge said the plaintiffs failed to satisfy a requirement that a shareholder suing on behalf of a company and seeking to hold top officials accountable must first demand that the board take action itself, or demonstrate why such a demand would be futile.
The faulty switches have been blamed for scores of deaths and injuries. GM knew about them for more than a decade but didn't recall them until early 2014.

The company said last year that the scandal, which prompted hundreds of lawsuits and a federal criminal probe, has cost it more than USD 5 billion.
