Also IIRC there was a case before the Supreme Court where the dispute was whether shareholder value was the sole & supreme goal, or there could be other factors involved from other stakeholders (such as workers, the community, ...).

The Supremes ruled for shareholder value.

However I forget details of ths case. If anyone here happens to know what case I am referring to, please chime in.

I don't know of a case where the Court affirmed shareholder primacy - as far as I am aware it's a state by state thing though since Delaware has it in their code it impacts a massive number of corporations.

You are probably thinking of the case described in GP, which is the decision of the Michigan Supreme Court on this issue.

I should have added, this was a case back in the 1980s.
