It may be common sense that a person is responsible for consequences caused by their actions. One reflection of this common understanding in legal principles, referred to by lawyers as the “Egg-Shell Skull” Rule, may lead to financial burdens unexpected by people who can be deemed responsible for the events. To understand this Egg-Shell Skull Rule, it is first necessary to know the importance of “causation” in pining legal liabilities to a person.
In situations where a person’s behavior has caused someone else to suffer loss or harm, causation is a crucial element of liability because it connects an injury to a responsible party. This makes sense because if A hit B in the arm and B suffered a fracture, naturally A would be responsible for the injury. Yet if A threw a light kick at the shin of B, who, unknown to A, had a series condition that set of a chain of events that finally resulted in B unable to use his leg at all, A may find herself held responsible for this grievous injury.
The Egg-Shell Skull Rule literally means that if B had a skull as delicate as that of the shell of an egg, and A, unaware of this condition, injured B’s head, causing the skull unexpectedly to break, A would be held liable for all damages.
