AH0680 - Preparation for Hearing: Summoning of witnesses


The Commissioners have the power to summon a witness either to give evidence or to produce documents in his possession, on the application of a party to the appeal. If possible, the question of whether a summons should be issued should be dealt with at a preliminary hearing (see AH0665).

The regulation makes it clear that any person who is summoned is the witness of the party at whose request he was summoned (the summoning party). He may not be cross-examined by that party except in the very rare circumstances where the Commissioners decide he should be treated as a hostile witness. `Hostile' in these circumstances has the legal meaning that the witness bears a hostile `animus' (intent or motive) to the summoning party and so may not give his evidence fairly or with a desire to tell the truth. In other words the witness is being deliberately unhelpful and uncooperative to the tribunal and the party calling him. It is not enough that the witness is merely being unhelpful.

A witness who is summoned cannot be compelled to give evidence or produce documents which he could not be compelled to produce in a court of law (see AH0720 for further advice on what this means in practice).

A witness who has been summoned is entitled to apply to the Commissioners to set the summons aside but the summoning party is entitled to be heard on any such application. If a witness who has been summoned fails to attend the hearing, or attends but fails to be sworn or affirm, or fails to answer any lawful question or produce required documents, then the Commissioners may award a penalty against him.

In the case of Tilbury Consulting Ltd (SPC379/03) the agent for the appellant company objected to the HMRC’s application for a witness summons and argued that if a summons were issued there would be a commercial risk to the appellant company. The Special Commissioners decided that although they have discretion as to whether to issue a witness summons, the presumption must be that they will grant such an application. The Special Commissioners also gave examples of circumstances in which an application might be set aside.

In Scotland, a witness summons is called a witness citation and sub-paragraphs (4) and (5) of the Regulation (not cross-examining your own witness and hostile witness) do not apply. In Scotland, the expression `hostile witness' has no technical meaning. When a witness in a Scottish case gives evidence damaging to the summoning party, that party is free to challenge the witness's evidence by suggesting to him that in specified respects it is mistaken, unreliable or untruthful, and may ask the Commissioners to disbelieve any part of it. He does not require the leave of the Commissioners to do this.

Normally it is not necessary to ask the Commissioners to issue a formal summons as each side will make arrangements for its own witnesses to attend voluntarily. However it can happen that a potential HMRC witness who is willing to give evidence may prefer to do so under the formality of a summons. In those circumstances you should ask the Clerk to arrange for a summons to be signed by the Commissioners. It is then your responsibility to serve the summons on the witness and they must be given at least seven days notice of the hearing.

The HMRC is responsible for meeting the expenses of any witness who attends a hearing to give evidence for the HMRC (whether voluntarily or under compulsion of a summons) and these can include travel, subsistence and reimbursement of any loss of earnings. You should ask for a detailed claim and this should be paid from the local budget. In any case where it appears that the expenses of a particular witness are likely to be substantial you should consult Central Policy: Tax Administration Policy before making any firm arrangements for that witness to give evidence for the HMRC.

You should also consult Central Policy: Tax Administration Policy, in any case where a potential and vital HMRC witness indicates he is not prepared to give evidence.
