Olympus shareholder suit filed

According to Reuters, an Olympus shareholder has now sued the board for "damaging trust" due to the accounting scandal there.   Of course, the board has already filed suit against itself, so I wonder where this suit stands.  I'm no expert in Japanese corporate law, in fact I know almost nothing about it.  Any readers from Japan - and we have a number - who wish to comment on how this shareholder suit stands next to the board's suit, please feel free.
