The answer is "Contributory negligence".
Contributory negligence is a rule of law that has been generally canceled in the U.S., as it considered that an offended party who was even halfway to blame for the episode, because of his own carelessness, couldn't recoup any harms from the litigant, who probably caused the occurrence.
In the U.S., contributory negligence was truly a guard to a claim asserting harms caused by carelessness with respect to the respondent. Fundamentally, this guideline kept up that if an offended party, through some carelessness of his own, contributed in any capacity to the mischief he endured, he might be denied pay totally. The standard of contributory negligence could be connected to a case by the court, regardless of whether it was asserted as a resistance amid the preliminary.
