Burden of Proof in UK Law

He has open to him the third alternative of saying that the party on whom the burden of proof lies in relation to any averment made by him has failed to discharge that burden. No judge likes to decide cases on burden of proof if he can legitimately avoid having to do so. There are cases, however, in which, owing to the unsatisfactory state of the evidence or otherwise, deciding on the burden of proof is the only just course for him to take.

I regard this last consideration as one of great importance for surely Parliament can never lightly be taken to have intended to impose an onerous duty on a defendant to prove his innocence in a criminal case, and a court should be very slow to draw any such inference from the language of a statute.

Proof that the complainant placed trust and confidence in the other party in relation to the management of the complainant's financial affairs, coupled with a transaction which calls for explanation, will normally be sufficient, failing satisfactory evidence to the contrary, to discharge the burden of proof. In other words, proof of these two facts is prima facie evidence that the defendant abused the influence he acquired in the parties' relationship.

The former requires the accused to establish his innocence. It necessarily involves the risk that, if the jury are faithful to the judge's direction, they may convict where the accused has not discharged the legal burden resting on him but left them unsure on the point. This risk is not present if only an evidential burden is created.

Throughout the web of the English Criminal Law one golden thread is always to be seen that it is the duty of the prosecution to prove the prisoner's guilt subject to what I have already said as to the defence of insanity and subject also to any statutory exception.

What is meant is (i) that the claimant must supply a plausible evidential basis for the application of a relevant jurisdictional gateway; (ii) that if there is an issue of fact about it, or some other reason for doubting whether it applies, the Court must take a view on the material available if it can reliably do so; but (iii) the nature of the issue and the limitations of the material available at the interlocutory stage may be such that no reliable assessment can be made, in which case there is a good arguable case for the application of the gateway if there is a plausible (albeit contested) evidential basis for it.
