My understanding is those kind of cases aren't common because a) they are hard to prove, b) the people being sued if they actually have the money to make it worth suing them also have the money to fight it, and c) it's a really bad look for an investor to be suing a previous member of their portfolio and would a strong adverse affect on their deal flow
Unless you're saying there is no explicit legal obligation / fiduciary duty in law, but it does emerge from civil court cases, which is how I understand it, but short paragraphs are not a good place for the amount of nuance so I just said "legal obligation" as a shorthand for something real but very complex.
Activist investors will sue for anything alleging that executives broke securities law by doing anything that harmed their portfolio. It doesn't mean they win the cases, or that anyone is guilty.
There's also something worth noting that even if there isn't a legal obligation for executives to act on their shareholders interests, they have a really strong incentive when their compensation is mostly stock grants and the shareholders can fire them.

> The Court declared that, in certain limited circumstances indicating that the "sale" or "break-up" of the company is inevitable, the fiduciary obligation of the directors of a target corporation are narrowed significantly, the singular responsibility of the board being to maximize immediate stockholder value by securing the highest price available.
Seems to imply that under normal operation (i.e. no inevitable break-up) the fiduciary obligations are quite different though?
- act in good faith;
- act in the best interests of the corporation;
- act on an informed basis;
- not be wasteful;
- not involve self-interest (duty of loyalty concept plays a role here).
