Contributory negligence (Art. 2179, NCC)

Article 2179 of the Civil Code reads:
Art. 2179. When the plaintiffs own negligence was the immediate and proximate cause of his injury, he cannot recover damages. But if his negligence was only contributory, the immediate and proximate cause of the injury being the defendant's lack of due care, the plaintiff may recover damages, but the courts shall mitigate the damages to be awarded.
Verily, contributory negligence is conduct on the part of the injured party, contributing as a legal cause to the harm he has suffered, which falls below the standard to which he is required to conform for his own protection.[1]
