Where the prosecution fails to impeach contradictory state witnesses and instead leaves the trial court to pick and choose which evidence to prefer, this constitutes a gross irregularity because the onus is on the State to prove its case beyond reasonable doubt. Where two reasonable possibilities exist on the evidence, and the trial court rejects the accused's corroborated version without cogent reasons, the conviction cannot stand. In theft cases, the element of permanent deprivation must be clearly established, and where the complainant himself has not ascertained what is due to him, the conviction for theft of trust property is not sustainable. Criminal prosecution is inappropriate for resolving what are essentially civil commercial disputes between parties to a business transaction.
