The High Court has ruled that unchallenged evidence in a criminal trial is not automatically decisive, but must be weighed as part of all the evidence. It said a trial judge may prefer other evidence, provided the unchallenged testimony is not ignored and the prosecution’s burden of proof is applied.
The ruling arose from a consultative case stated sent by a District Court judge during the trial of Karl Burke and Mark Burke. The men faced charges relating to an alleged assault, attempted assault and production of a hammer with intent to intimidate or assault another person. The High Court was asked to answer legal questions about evidence given by a prosecution witness; it did not determine the charges or decide whether a conviction would be correct.
The prosecution alleged that Mark Burke confronted three people over an alleged attempted car theft the previous week, and that Karl Burke assaulted one of them during the confrontation. It further alleged that Mark Burke retrieved a hammer from a van and threatened another person. Karl Burke said he was not at the scene and offered an alibi witness. Mark Burke accepted he was there and confronted one person, but denied producing or owning a hammer. These were the parties’ positions as described in the judgment, not findings by the High Court.
The witness at the centre of the questions, Tara Burke, was Mark Burke’s wife and Karl Burke’s sister-in-law. The prosecution called her to establish that she had made a 999 call. She gave evidence consistent with statements she had previously made to gardaí that were exculpatory of both accused. The prosecution did not challenge that evidence. The two accused cross-examined her.
The High Court said there was no rule requiring a party to cross-examine a witness. But evidence left untested and uncontradicted carries greater weight and cannot be disregarded. The trial judge, as the finder of fact, still had to assess all the evidence and decide whether the prosecution had proved the charges beyond reasonable doubt. The court said the witness’s evidence was important but was not automatically conclusive.
The judge also rejected treating Tara Burke as a hostile witness “in effect”. No formal application had been made to have her treated as hostile, and the court said the law did not recognise an informal equivalent. It answered the first question “Yes”, while making clear her evidence could not be ignored; answered the second “No”, saying she was not hostile; and said the third question did not arise. The High Court did not direct the District Court judge to prefer either version of events.
