A more thorough explanation:

Dissenters' right is a legal term that refers to the right of corporate shareholders who oppose some extraordinary corporate action, such as a merger, to have their shares judicially appraised and to demand that the corporation buy back their shares at the appraised value. This is also known as the appraisal remedy.

For example, if a company decides to merge with another company, some shareholders may not agree with this decision. In such a case, those shareholders can exercise their dissenters' right and demand that the company buy back their shares at a fair price.

The dissenters' right is a way for shareholders to protect their interests and ensure that they are not forced to accept a decision that they do not agree with. It gives them the option to exit the company and receive a fair value for their shares.
