Res inter alios acta

RES INTER ALIOS ACTA, evidence. This is a technical phrase which signifies acts of others, or transactions between others.
     2. Neither the declarations nor any other acts of those who are mere strangers, or, as it is usually termed, any res inter alios ada, are admissible in evidence against any one when the party against whom such acts are offered in evidence, was privy to the act, the objection ceases; it is no longer res inter alios. 1 Stark Ev. 52; 3 Id 1300.
