What is an unfair trade practice where one party refuses to engage in business unless certain conditions are met?

The practice described is characterized by one party placing unreasonable conditions on the engagement of business with another party, which is precisely what a boycott entails. A boycott occurs when a group or individual refuses to deal with a business or organization to put pressure on that entity to change a specific practice or policy.

In this context, the term refers to the refusal of an insurer or a provider to offer services unless certain conditions are met, thus leveraging their position to influence the other party's decisions. This behavior can be seen as an attempt to manipulate the market or the choices available to consumers, which is why it is labeled an unfair trade practice.

Each of the other terms refers to different concepts. Coercion implies forcing someone to act against their will, discrimination typically involves unfair treatment based on specific characteristics, and fraud relates to deceptive practices intended to secure an unfair gain. None of these fits the specific scenario of refusing to do business under certain conditions in the same way that boycott does.
