A witness summons, sometimes called a subpoena, is a court order requiring a person to attend court or produce documents as evidence in a legal dispute. For your business, it is a powerful tool to secure critical evidence, but it also creates strict legal obligations, as failure to comply can result in penalties and procedural consequences. You must use it strategically and ensure compliance if served. This article explains what a witness summons is, when it can be used and how it operates in England and Wales.

What is a Subpoena?

A subpoena is issued when a court requires a person to submit oral evidence as part of a trial. Failure to provide the evidence can result in a penalty to the summoned individual. In fact, the word ‘subpoena’ means ‘under penalty.’ 

The English legal system currently prefers the term ‘witness summons’ over ‘subpoena.’ However, many people still recognise the meaning of a witness summons through the word ‘subpoena’.

How Would I Summon a Witness Normally?

Normally, witness summons are used in criminal proceedings. A witness supporting the prosecution’s argument will be the prosecution’s responsibility. This means that the prosecution will have to ensure that their witness turns up in court. Similarly, a defence team will have to make sure that their defence witness turns up in court.

However, if the witness refuses to turn up to court for whatever reason, you may consider applying for a witness summons. First, it is a good idea to speak to witnesses and get information about their reasons for not attending court. 

If the witness is worried about turning up to legal proceedings because of their own fear or anxiety, you can apply for ‘special measures’ at the court. This involves the court providing alternative ways to hear the witness’s testimony, such as via video link. 

However, if this does not work, you may consider applying for a witness summons. This can help the requesting party to make the witness give a testimony in court where they physically appear.

Applying for a Witness Summons

Either the defence or the prosecution can apply for a witness summons, which will require the witness to come to court or pay the penalty. 

To successfully obtain a witness summons by the court, the court must be satisfied that:

  • the evidence that the witness is going to give is likely material evidence that could prove something relevant in the case; and
  • the witness summons will be in the interests of justice. For example, it may enable tangible evidence to be presented in court. 

However, if the court thinks that a witness cannot give evidence, they will not grant a witness summons. This may occur, for example, if the court believes the witness is not competent or compellable.

An application for a witness summons is made in writing and typically does not require a hearing. A court can serve a summons to any individual mentioned in the application. It does not necessarily have to be the specific individual the prosecution or defence has asked for within the application.

Once the court grants the application, an appointed person will serve the summons to the witness. This is usually done through personal delivery or a letter to the witness’s address. They must then attend the court at the time and date specified. 

Objecting to a Witness Summons

A witness that has been served with a witness summons can apply to set the summons aside. They may be able to do so because they:

  • were not aware of any application made by the client’s lawyer for a witness summons; and
  • cannot give in any evidence which is likely to be relevant to the case; or
  • the rights of confidentiality of the witness outweigh the reasons for issuing a witness summons.

On the whole, a witness summons can help convince a reluctant witness into giving evidence that may support your case. This is most often used in criminal proceedings. In any case, you should seek legal advice before considering taking steps to convince a witness to testify.

Key Takeaways

You may find yourself in a court dispute at some point in your business’s lifespan. In this instance, it can be a good idea to explore different ways of getting a witness to give a testimony. One way is talking directly to the witness, but if this does not work, you may consider applying for a witness summons.
