Abstract: In civil litigation, it is always difficult for a judge to compare the weight of evidence of conflict conclusions provided by different experts. Before deciding which expert's witness is more admissible, a judge needs to compare different expert conclusions in respect of the external weight of evidence, the internal weight of evidence and, especially, the synthetical weight of evidence. When the direction of external weight of evidence is contrary to that of internal weight of evidence, the latter should be decisive.

Key words: civil litigation, the conclusion of expert witness, the weight of evidence
