No jurisdiction allows a death claim for suicide according to the strict definition of the term. When death benefits are paid to a decedent's dependents for death produced by his own hand, the term "self-destruction" rather than suicide is applicable. To allow recovery, all jurisdictions require that the decedent be subject to some mental derangement at the time of the commission of the act. It is the degree of derangement required, the manifestation of it, and the causal relationship of it to the compensable injury which create problems.
