STANDARD OF PROOF IN CRIMINAL PROCEEDINGS

BURDEN OF PROOF ON HE WHO ALLEGES POSITIVE

The law is elementary that the burden of proof is on the party who alleges the affirmative. Whoever desires any court to give judgment as to any legal right or liability dependent on the existence of facts which he asserts must prove that those facts exist.

WHERE ACCUSED PLEADS GUILTY PROSECUTION BURDEN BECOMES LIGHT

OMOJU v. FRN (2008) LPELR – 2647 (SC), Tobi JSC (of blessed memory), considered the effect of an accused person’s plea of guilt on the burden placed on the prosecution where my noble Lord held thus: “The law is elementary that if an accused person pleads guilty, the burden of proof placed on the prosecution becomes light, like a feather of an ostrich. It no longer remains the superlative and compelling burden of proof beyond reasonable doubt. After all, the guilty plea has considerably shortened the distance and brought in some proximity the offence and mens rea or actus reus of the accused as the case may be. That makes it easier to locate causation or causa sine qua non.”

THE TWO DISTINCT MEANINGS OF BURDEN OF PROOF

This position reminds one of the decision of this Court in Elemo v Omolade (1968) NMLR 359, where it was held that burden of proof has two distinct and frequently confusing meanings. It means: (a) the burden of proof as a matter of law and pleadings; the burden as it has been called of establishing a case whether by preponderance of evidence or beyond reasonable doubt; and (b) the burden of proof in the sense of introducing evidence. As regards the first meaning attached to the term, “burden of proof”, this rests upon the party whether plaintiff or defendant who substantially asserts the affirmative of the issue. It is fixed at the beginning of the trial by the state of the pleadings and it is settled as a question of law, remaining unchanged throughout the trial exactly where the pleadings place it and never shifting in any circumstances whatever. In deciding what party asserts the affirmative, regard must be had to the substance of the issue, and not merely to its grammatical form which later the pleader can frequently vary at will. A negative allegation must not be confounded with the mere traverse of an affirmative one. The true meaning of the rule is that where a given allegation whether affirmative or negative forms an essential part of a party’s case, the proof of such allegation rests on him. While the burden in the first sense is always stable, the burden of proof in the second sense may shift consistently more as one scale of evidence or the other preponderates. In this sense, the onus probandi rests upon the parties who would fail if no evidence at all or no more evidence is gone into upon the party asserting the affirmative or the party against whom the tribunal at the time the question arises would give judgment if no further evidence were adduced. The test as to who is to begin is determined by asking how judgment would be entered on the pleadings if no evidence at all were given on either side. The party against whom judgment would in that event be given is entitled to begin.
