Problems with using video link evidence in courts could affect front-line policing and cost the taxpayer money, the Police and Crime Commissioner for the Thames Valley has warned.

The issues regarding “virtual courts” and the possible closure of some courts - including in Bucks - have been scrutinised by Anthony Stansfeld, who says it is “considered essential that local trial courts are maintained”.

However, the Commissioner says an increase in the use of video links and digital technology should be welcomed, unless it becomes an excuse to close or remove local courts.

Mr Stansfeld said: “It remains that video links and technology have a significant role to play in improving the efficiency and costs of the administration of justice.

“However, unless the potential issues with the use of video links in contested trials are fully addressed, it may not remove the need for police officers and witness to attend trials in person.

“Therefore while the closures of local courts may not be so significant in terms of preliminary hearings and case management, it could cause significant time and costs implications for police officers, victims and/ or other witnesses who have to travel greater distances to attend court in person.

“For this reason it is considered essential that local trial courts (whether held at Magistrates’ Court or other venues) are maintained.”

In July it was announced that the government were holding a consultation on plans to close 91 courts and tribunals in England and Wales.

Aylesbury Magistrates’ Court could be amongst those facing closure if plans were agreed. Mr Stansfeld also highlighted a series of issues that have been connected with the use of video links in court.

These included that a delay in transmission, poor quality and/ or angles could lead to witnesses being talked over and could impact on the assessment of a witness.

Mr Stansfeld said: “There are similar issues that will have to be considered by Criminal Courts if video links are to become the norm because witnesses or officers are no longer able to attend a local court (due to court closures).

“It is envisaged that there will be a number of cases where the courts will rule that an efficient and fair trial can only take place is witnesses attend in person.”

He added: “If video links are to become standard practice because of court locations/ closures, not only may a number of cases not be allowed to proceed with the use of video links due to the nature of the case but court time could also become further burdened with the requirement to deal with and adjudicate on increased numbers of applications for/ against the use of video links.”
