XP v Public Prosecutor: Outrage of Modesty, Standard of Proof, and Witness Credibility

XP appealed against his conviction by the High Court on three charges of outrage of modesty under Section 354 of the Penal Code. The charges involved two complainants, E and D, who were students at the school where XP was a teacher. The High Court, Rajah JA, allowed the appeal, finding that the convictions were based on conflicting evidence and that there were reasonable doubts concerning XP's guilt. The court emphasized the importance of the presumption of innocence and the prosecution's burden to prove guilt beyond a reasonable doubt.
