DURESS. Where the contract is assented to by one of the parties by rea son of his being coerced by actual or threatened vio lence, it is duress, and the party coerced may avoid it. What constitutes duress has been explained in a pre vious volume of this series, and need not be repeated !ere. (Vol. 3, Sec. 254, Home Law School Series.) The duress to be ground of avoidance of the contract must affect the promisor and not some third person, and it must be a personal injury which is impending and an injury to property. (Anson on Cont. p. 164.) See Blackly- v. Headly, 45 Mich. 570.
