1. When an accused alleges incompetent legal representation violating the right to a fair trial, the legal representative's response is admissible through imputed waiver of privilege to the extent necessary for fair evaluation of the allegations. 2. Where an accused's allegations against counsel do not raise a real possibility of incompetence, bad advice, or misconduct, they may be rejected without further inquiry based on inherent implausibility and contradictions. 3. An accused's constitutional right to remain silent does not prevent the drawing of adverse inferences in appropriate cases where circumstantial evidence calls for an explanation that the accused is in a position to give. 4. Under s 35(5) of the Constitution, real evidence obtained through torture, assault, and coercion must be excluded as it both renders the trial unfair and is detrimental to the administration of justice, regardless of the distinction between 'real' and 'testimonial' evidence. 5. Evidence obtained through deliberate and flagrant rights violations, particularly involving compulsion or torture, is inadmissible as it undermines the moral authority of the justice system. 6. Dock identification, while generally suspect, may be sufficient to sustain a conviction where there was extensive and protracted contact between witness and accused, corroborating circumstances, and the overall quality of the witness's evidence is reliable.
