Consistent, categorical, straightforward, spontaneous, frank testimony shows credibility

A witness who testifies in a categorical, straightforward, spontaneous and frank manner and remains consistent is a credible witness. The candid and unwavering narration by the victim here of how she was raped, as borne out by the records and the transcript of stenographic notes, bears the earmarks of credibility. We are satisfied that Rosalina Orubia, the hapless complainant, is a credible witness and that her testimony is worthy of judicial acceptance. [G.R. No. 118823. November 19, 1996]
