The Court of Appeal has dismissed Slawomir Gierlowski’s appeal against his conviction for assault causing harm, false imprisonment and producing a flex capable of inflicting serious injury in an attack at Ballymount Park. The judgment, delivered on 21 April 2026, found no basis to overturn the jury’s verdict.

The court held that the trial judge had not erred in admitting the inference interview or in leaving the circumstantial evidence for the jury to consider. It also concluded that a properly directed jury could have returned a guilty verdict. The case against Gierlowski included a partial fingerprint match on the flex and a DNA match on a cigarette box recovered in the park.
