(2) (a) "Conclusive evidence" is that which the law does not permit to be contradicted.
(b) No evidence is by law made conclusive unless so declared by statute.
(3) "Corroborative evidence" is additional evidence of a different character to the same point.
(4) "Cumulative evidence" is additional evidence of the same character to the same point.
(5) "Direct evidence" is that which proves a fact without an inference or presumption and which in itself, if true, establishes that fact.
