“Where the participant is abroad, then (depending on the country concerned) the court will wish to consider whether a live link would risk damaging international relations so as to be contrary to the public interest. The factors to consider, and the checks that can be made, are set out in Agbabiaka (evidence from abroad; Nare guidance)[2021] UKUT 00286 (IAC) .”
“Some countries will allow requests to be arranged and conducted through informal channels, through a police to police basis, or even via direct contact with the witness from the UK. However, in many countries, a direct approach to a voluntary witness is not permitted and an ILOR will be required to establish a live link at trial. Many countries will rarely, if ever, make use of live link in criminal proceedings and will not have the necessary equipment. In these cases, it is vital that the prosecutor considers these issues at an early stage as it is probable that the request to set up a live link in such cases will take many months of planning. In some countries a live link will not be technically possible, although is possible that the requested state will allow the UK to supply the necessary equipment and expertise.”
