Answer:
No Alder will not be able to enforce the release
Step-by-step explanation:
In the given scenario Alder is trying to use duress and blackmail techniques to force Perreault to release him from his debt obligations.
However Perreault induced by fear gives Adler a release but subsequently sues to set it aside and recover on his claim.
Alder will not be able to enforce the release because it was obtained under duress.
Under contract law the release is not valid.
