The Supreme Court allowed Michael Tyndall’s appeal and quashed his conviction and 12-year sentence after finding there was no evidence that the arresting garda had the suspicion required to make a valid arrest under section 30 of the Offences Against the State Act 1939.
The appeal concerned the proof of suspicion where the prosecution had been put on notice that the arrest was challenged. The Court held that suspicion is a condition of a valid section 30 arrest. It need not be proved in a particular form: it may be established by direct evidence or inferred from the circumstances. But there must be evidence beyond the arrest itself from which the suspicion can be inferred.
Tyndall had been convicted in Dublin Circuit Criminal Court of firearm possession with intent to commit robbery, robbery and intentionally or recklessly causing serious injury. The prosecution alleged that he was one of two men who entered James Mahon’s home on 9 April 1999; one man had a knife and gun, and Mahon was stabbed and badly injured. Tyndall pleaded not guilty.
At trial, Detective Sergeant Patrick Campbell testified that he went to Tyndall’s home, identified himself and arrested him under section 30 for unlawful possession of firearms. He gave no direct evidence that he suspected Tyndall of a scheduled offence. The trial judge inferred suspicion from the officer’s role in the investigation, his knowledge of the case and his decision to make a section 30 arrest. The Court of Criminal Appeal upheld that conclusion, finding the inference open on the evidence.
The Supreme Court rejected that inference. Denham J, delivering judgment, said the officer’s status as an investigating detective sergeant and the fact that he made the arrest were insufficient. Relying on the arrest itself to establish a condition that had to exist before the arrest would be circular. The Court said circumstances other than the arrest were needed, and none had been put before it.
The Court answered that the Court of Criminal Appeal was wrong to find the arrest valid on this record. It confirmed that suspicion may be inferred where the circumstances provide proof, and that section 30 does not require formal oral evidence in specific words. It did not rule out inference in other cases.
The Court set aside the Court of Criminal Appeal’s order, granted leave to appeal, treated the leave application as the appeal hearing, and quashed the Circuit Court conviction and sentence. It did not consider the other, uncertified grounds of appeal.
