Article 161 Any person who would otherwise be liable under the provisions of this Chapter shall be exonerated from the liability for damage if he proves that the damage was caused solely by the fault of the person who suffers the damage or of the latter's servants or agents.
If the person liable proves that the damage was contributed to by the fault of the person who suffers the damage, or of his servants or agents, the compensation shall be reduced to the extent to which such fault contributed to the damage.
Nevertheless, there shall be no such exoneration or reduction if, in the case of the fault of a servant or agent, the person who suffers the damage proves that his servant or agent was acting outside the scope of his authority.
Where an action is brought by one person to recover the damage arising from the death or injury of another person, and the damage was caused by the fault of such other person, or of his servants or agents, the provisions of the preceding paragraph shall apply.
