Keep in mind that these are the facts as alleged by the Plaintiff. It is not “what happened”.
As TD points out, the “Board” is not a neutral party here, and is probably led by the company’s investors, who prominently include a VC fund.
The central allegation seems to be that some elements of expenditure on the plant were not declared to the company, although it is acknowledged that others were. That is obviously something that will need to be tested.
