Cases

• R v EA (May 2023) David Langwallner acted in a multi handed two week case at Wolverhampton Crown Court, involving allegations of abuse by carers in a care home.  The case involved complex assessment of care home policy, training, and staffing, as well as legal argument about the crucial distinction between the test for criminal recklessness and a breach of the common law duty of care for the purposes of a civil claim in negligence. David, who was instructed by Duncan Lewis Solicitors, was able to secure an acquittal for his client.
• RR v PD  (May 2022 ,Croydon Crown Court ) David secured an acquittal on multiple rape allegations involving complex family issues. He was expressly compliment by the trial judge for his handling of the case.
• ( In The Court Of Appeal 2021) David Langwallner recently secured a substantial reduction in the sentence of a man convicted of causing grievous bodily harm with intent.  The Court of Appeal agreed that the sentencing judge in the court below had failed to properly evaluate the implications of a psychological report which had confirmed a diagnosis of autism; the judge had further failed to properly engage with the implications of previous abuse suffered by the defendant, which may have caused him to misconstrue the complainant’s intentions.  The Court accordingly reduced David’s client’s sentence from 11 years’ imprisonment to 8 years’ imprisonment.
• R v HS (April 2019, Blackfriars Crown Court) – secured an acquittal on serious allegations of sexual assault against a thirteen-year-old boy;
• R v PA (February 2018, Isleworth Crown Court) – secured an acquittal on the basis of self-defence and proportionate force arising out of a charge of actual bodily harm in a domestic situation. In this respect David implicitly relied on such cases as Beckford (1995) and Owiko (1995), in which it was held that the defence of self-defence is to be assessed objectively in terms of the proportionality of the force used but with a subjective complement in terms of the accused’s perception of the situation, his instinctive reaction through violence or a perceived threat of same and above all with respect to the individual circumstances of the case. David also relied on Lord Sankey’s judgement in Woolmington v DPP and the concept of cognitive or confirmatory bias;
• R v CD (January 2018, Snaresbrook Crown Court) – secured an acquittal in a blackmail case relying implicitly on such cases as R v Clear (1968) and R v Astig (2015) on the ambit and definition of menaces and reasonable demands in the context of payment for drug monies owed. David addressed the jury in detail on questions of corroboration and credibility and how proof is made out or not;
• Case of BK (2019) – before the Committee of Mercy on a death penalty matter in Kenya;
• Harry Gleeson (2015) – secured the first posthumous pardon in the history of the Irish state;
• David secured an acquittal in the Old Bailey in an allegation of sexual exposure. The case involved assessments of credibility and detailed testing of the evidence of the complainant. There was no dispute as to presence or identification of the defendant (2018).
