Areas of Expertise

Peter deals with heavyweight criminal work, both defending and prosecuting. He regularly receives instructions in the most serious cases, including murder, attempted murder, manslaughter, rape, historic sexual offences, child abuse, arson with intent to endanger life, firearms offences, drugs offences and fraud.

He has acted either alone or as leading advocate in several murder cases, and in many others led by Queen’s Counsel. Whilst the majority of his work is in the Crown Court, he also has a long record of effectively representing private clients in the magistrates’ court, including motorists and pub landlords.

He has also acted in regulatory and trading standards cases. He has frequently appeared in the Court of Appeal, and has also dealt with appeals to the Administrative Court in criminal cases by way of case stated and judicial review.

Notable cases

In 2017 Peter defended IS, who was charged with rape.  The defence was consent.  There was CCTV evidence showing the demeanour of the complainant, repeatedly choosing to put herself in the company of the defendant during the hour or so following the relevant events.  This was used to good effect.  Peter was able to cross examine the complainant and her violent partner as to matters of bad character, which revealed very different reasons as to why she might have been intimidated into making a complaint of rape. IS was acquitted after trial.

Between 2015 and 2017 Peter defended Natasha Frazer who was one of 21 defendants charged with a Category 1 Class A drugs conspiracy, extending across wide areas of the Midlands.  A Wolverhampton based gang were moving large scale heroin and cocaine operations into other towns.  Organised crime group leader Michael Porter received 20 years’ imprisonment. Frazer was described by the prosecution as one of his senior lieutenants. The evidence was strong and the papers were very extensive: 17,633 pages in total.  It was vital to identify key exhibits early and offer appropriate advice.  This was done and Frazer pleaded guilty at an early stage on a basis, attracting full credit.  Considered mitigation resulted in a sentence of just 40 months’ imprisonment: significantly lower than others in the case.

In 2016 Peter, leading Anthony Cartin of St Ives Chambers, defended Marcus Woolcock.  Marcus Woolcock was one of 5 men charged with multiple rapes and the trafficking for sexual exploitation of six young females.  The case involved over 10,000 pages of evidence and even more unused material.  Peter and Anthony’s repeated disclosure requests uncovered vital material.  They successfully applied to cross examine complainants on sexual behaviour. The case involved exceptionally sensitive cross examination of young complainants.  Successful submissions of ‘no case to answer’ were made in respect of one rape and two trafficking counts. Ultimately, Woolcock was acquitted of ten counts: six rapes, three trafficking counts and one count of assault by penetration. He was convicted of two counts only, namely sexually assaulting and trafficking a single complainant, which were the least serious counts he had faced.

Between 2014 and 2016 Peter prosecuted G, who was 17 at the time of the offences, on three charges of attempted murder: G had repeatedly stabbed his mother and two young sisters, causing terrible injuries. The case was prepared for trial but ultimately the prosecution accepted pleas to three offences of wounding with intent to cause grievous bodily harm.  Following a succession of psychiatric reports, a ‘Newton’ hearing ensued, with the issue being whether excessive consumption of ‘energy drinks’ could have triggered a temporary psychosis in G.  The medical issues were such that the case was described by two experienced forensic psychiatrists as “the most complex case we have seen”.  Some 12 psychiatric reports from five different consultant psychiatrists were considered. The trial of issue required exceptionally skilled cross examination of defence consultant forensic psychiatrists.  The defence psychiatrist’s opinion that G had suffered a psychosis because of his excessive consumption of energy drinks was rejected. G received life imprisonment.

Also in 2016, Peter represented high profile defendant Kelly Mahon, who had snatched a nine-week-old baby after an elaborate deception. Mahon believed her boyfriend wanted a child, and she could not bring herself to tell him she could not have children.  She feigned a pregnancy and stole a baby. Thankfully the baby was swiftly recovered by prompt police action.  This sad background founded powerful mitigation.  Peter obtained a psychiatric report, which helped achieve a much lighter prison sentence than might have been imposed.

Also in 2016, Peter prosecuted Damian Malolepszy for being concerned in supplying Daniel Bagnall with Class A drugs which caused his death. The drugs were the notorious ‘Superman’ PMMA tablets which caused at least three deaths in Suffolk and one in Shropshire around New Year 2015. Numerous obstacles were overcome in relation to a series of reluctant, frightened and hostile prosecution witnesses, and Peter coaxed vital admissible evidence from each. Complex legal arguments were necessary in relation to bad character, the admissibility of the evidence of Bagnall’s death, the admissibility of evidence of hostile witnesses and reporting restrictions.  Malolepszy was convicted and received a long prison sentence.

In 2015 Peter defended a man, TT, in a medically complex “baby shaking” case. TT was an inarticulate defendant charged with causing grievous bodily harm with intent, after his three-month-old son had been admitted to hospital with life threatening brain injuries. The case was prosecuted by Queen’s Counsel but Peter defended alone. There was extremely complex medical evidence embracing senior paediatric neurosurgeons, neuroradiologists, opthalmologists, and paediatricians. Skilled cross examination of numerous prosecution experts was required. The defendant was acquitted after a two week trial, the jury being persuaded that the injuries may well have been cause by an accidental fall downstairs, which was the defence case.

Also in 2015, Peter defended a 15-year-old boy, K, who was charged with rape of children aged three and five. Exceptionally delicate cross-examination of very young children revealed what police interviewers had failed to elicit: that the children were not distinguishing between penetration (on the one hand) and external touching (on the other hand). Following Peter’s cross examination there was no evidence of penetration and K was acquitted of all the rape charges after a submission of no case to answer. K was also acquitted of lesser ‘sexual activity’ charges involving the three-year-old child, after Peter pointed out to the jury the real risk of this child’s evidence having been contaminated by her hearing things said by her older brother. K was however convicted of the ‘sexual activity’ charges involving the elder child. Detailed mitigation restricted the sentence to a two year detention and training order.

Again in 2015, Peter defended a defendant, TB, in a hugely complex historic rape case. The alleged offences dated from the 1970’s, so the events were over 40 years old. Obscure but important legal provisions and presumptions, long since abolished, were researched and used by Peter to good effect. The complainant and two other witnesses were all profoundly deaf, which led to cross-examination taking place via two signing interpreters and a profoundly deaf intermediary. Peter’s submission that there was no case to answer on some rape counts was upheld. Peter’s detailed analysis of extensive medical records threw doubt on the credibility of the complainant, who had suffered from longstanding hallucinations and psychosis. The defendant was ultimately acquitted of all remaining counts by the jury.

In 2014 Peter defended Harry Card, one of a large group of men charged with two separate conspiracies to import cocaine and with conspiracy to import cannabis. One conspiracy alone involved an alleged agreement to import over 60 kilos of cocaine. Harry Card admitted involvement with cannabis (helping out his father in Spain years before) but denied any involvement in cocaine. Spanish telephone intercept evidence from 2007 and 2008 lay at the heart of the case. Two main offenders had pleaded guilty before trial but nine defendants were tried. The prosecution were represented by Queen’s Counsel and junior counsel, but Peter defended alone. The prosecution claimed that Harry Card’s role was central to the case and he was placed first on the indictment. The case involved more than 10,000 pages of evidence in addition to the transcripts and recordings of over 4,000 telephone calls. The telephone recordings were successfully explained to the jury and Card was acquitted of both cocaine conspiracies after a three month trial which concluded in January 2014.

Also in 2014, Peter was instructed to prosecute DE, a young man charged with the knife murder of a 15-year-old boy. Peter led another counsel in this trial, which attracted local and national media interest. The defendant was represented by Queen’s Counsel and a junior counsel. Several young frightened witnesses gave evidence assisted by special measures. There were significant issues concerning the admissibility of informal admissions and whether it was right that the judge should direct the jury on self-defence, even though it had not been relied on by the defence. The defendant gave evidence and was cross examined by Peter. He was convicted after trial and was subsequently refused leave to appeal.

Again during 2014, Peter prosecuted Akeel Hussain for murder. Peter acted alone, the defendant being represented by two counsel, a leading junior and a second junior. It was not in issue that the defendant had killed his partner by stabbing her 50 or 60 times, but there were complex medical issues of diminished responsibility, having regard to serious paranoid episodes. Those episodes were however, on the Crown’s case, brought on by heavy use of cocaine. After five days of trial the defendant changed his plea to guilty, shortly before the close of the prosecution case.

Also in 2014, Peter defended a young man, BK, in a murder which involved extraordinarily complex medical and causation issues. A man was assaulted, suffered head injuries, was discharged from hospital, but then died some three days later. At an early stage Peter was instructed alone, without a QC, and made an application to dismiss the murder charge on causation grounds, which at that stage was unsuccessful. Two murder trials subsequently ensued. Peter successfully obtained leave to instruct Queen’s Counsel and was led by Rachel Brand QC. At the first trial, BK and a co-defendant were both convicted of a lesser charge of causing grievous bodily harm with intent, but the jury could not agree on murder. At the re-trial for murder, submissions of no case to answer were successful in respect of both defendants, on causation grounds.

Again in 2014, Peter prosecuted Malcolm Blood for 17 historic sexual offences (rapes and indecent assaults) committed against two young children in the 1970s. The victims had not felt able to come forward until over thirty years after the abuse. Blood denied all charges but was convicted after a six day trial and was sentenced to serve 18 years’ imprisonment.

In 2013 Peter prosecuted a 13-year-old defendant, K, for the rape of a three year old child. At the first trial, the evidence of the toddler victim was ruled inadmissible and the jury was discharged. Successful legal submissions prepared by Peter led to the admission of hearsay evidence at a later re-trial, and the young defendant was convicted.

Also during 2013, Peter defended in the high profile and tragic child murder of four-year-old Daniel Pelka. Led by Stephen Linehan QC, he defended Magdalena Luczak, Daniel’s mother. The case received widespread nationwide TV and newspaper coverage throughout the two month trial, and on many occasions since. Both Luczak and her partner were convicted of murder, the prosecution having put their case on a basis of joint enterprise. The trial judge in her sentencing marks said, however, that she was satisfied that the co-accused Mariusz Krezolek had inflicted the fatal blows. By way of a footnote to this tragic case, both Luczak and Krezolek have since died in prison.

In 2012 Peter defended in a murder case where issues of the utmost sensitivity resulted in most of the trial being heard in private.  He also defended that year in a multi-million pound mortgage fraud, one of the largest to have been prosecuted in the UK.  He successfully prosecuted several defendants who had taken part in the 2011 August Riots.

Also in 2012, Peter prosecuted Mark Pickering, who was convicted after trial of the sexual assault of a child.  Before the Court of Appeal he successfully resisted Pickering’s appeal against conviction, in one of a consolidated series of landmark appeals concerning the admissibility of mixed profile DNA evidence.

Since 2011 he has appeared successfully in a number of high profile cases involving the alleged grooming and sexual abuse of teenage girls by gangs of older men. He has defended in some and prosecuted in others.  His cross examination of a young complainant in one such trial resulted in her admitting that she had made a false allegation in order to protect the true offender. The prosecution later offered no evidence against Peter’s client, TA, on that charge. The true offender was subsequently convicted after trial and was sentenced to 14 years’ imprisonment for a variety of serious offences against young girls.

In 2010 Peter defended David Evans, a man of good character who was charged with death by dangerous driving. At first sight, there appeared to be strong independent evidence against Mr Evans, who had already been advised by another barrister that he had little hope of an acquittal and should plead guilty. Mr Evans had himself been seriously injured in the fatal accident and had no recollection of the final moments before impact with the dead man’s vehicle. Peter advised the instruction of an accident reconstruction expert. Mr Evans was acquitted at trial after the independent witnesses were shown, through cross examination and the evidence of the defence expert, to have given flawed evidence, and quite probably to have been the cause of the fatal accident.

 Older cases of significance

Peter led Roger Thomas of St Ives Chambers in the successful defence of SW, one of the defendants in Operation Shepherd, a landmark £70 million “carousel fraud” trial which lasted for nine months.  The prosecution were represented by Queen’s Counsel and three junior counsel. Most of the other defendants in that case were convicted and lengthy prison terms were imposed.

Peter has expertise in DNA and cell site evidence and his cross examination of a cell site expert was instrumental in the acquittal of a man charged with the Birmingham gangland murder of Ezron Germaine.

Peter also has experience in prosecuting very large scale international immigration conspiracies, notably Operation Cirene and Operation Coptine.
