Notable cases

R v Reynolds (Nicholas) [2020] 4 WLR 16 [2020] 1 Cr App R 20, [2019] EWCA Crim 2145: the defendant, general manager of a UK subsidiary of a multinational engineering company, was convicted after a trial of corruption in relation to a contract to refurbish a power station in Lithuania. The Court of Appeal provided important guidance as to the purpose and nature of a summing-up of the evidence in the context of a long and complex trial where the evidence was presented electronically and where many of the facts were not in dispute. It was not usually necessary to remind the jury of points made in counsel's speeches, unless a defendant had not answered questions in interview or had not given evidence.

R v King  [2019] EWCA Crim 2199: complaint of trial counsel dismissed.  Conviction upheld and sentence of 18 years for conspiracy to supply class A (based on supply of cutting agents only) upheld.

R v W(G) [2018] 4 WLR 129: W was extradited to the UK from Sweden. He faced a single count of conspiracy to corrupt, contrary to the Criminal Law Act 1977 s.1. The alleged criminality spanned the period January 2002 to March 2010. Swedish law had a 10-year limitation period on criminal liability and consequently the Swedish court had only authorised the applicant's extradition in respect of his alleged conduct post May 2007. The SFO, however, sought to rely on evidence of the applicant's conduct pre-May 2007. On appeal by W, the Court of Appeal ruled that, in the context of a continuing offence, the rule of speciality did not preclude the prosecution from adducing evidence of conduct which fell outside the relevant time period to prove the commission of an offence which fell within it. The rule was concerned with offences, not evidence.
