Mr Vollenweider is Leading Junior Counsel.
High net worth individuals regularly instruct Mr Vollenweider in complex financial remedy cases involving international property portfolios and companies. He is used to dealing with family trusts and the tracing and recovery of assets allegedly dissipated.
He has been led by the Honourable Mr Justice Nicholas Francis K.C. of 29 Bedford Row in two of his cases before Sir Nicholas’s appointment. He has appeared, instructed alone, against Alexis Campbell K.C. of 29 Bedford Row in a £25million financial remedy claim concerning a long marriage, and has had the pleasure of working alongside Elizabeth McGrath K.C. of 3 Paper Buildings concerning a very short marriage and opposite Samantha Hillas K.C. of St John's Buildings, where he relied on an alleged completed agreement and the case of Xydhias v Xydhias  1 FLR 683. The case ultimately settled. He has been instructed as sole Counsel in a case where the wealth of the husband was allegedly £75 million.
He has appeared against Farrer & Co, solicitors to Queen Elizabeth II at the time.
He is often instructed by companies to intervene in financial remedy cases, where the husband is a director/shareholder of the company, and has appeared in cases involving allegations of fraud, where reference to the Director of Public Prosecutions is a real possibility.
He has appeared in applications under the Trusts of Land and Appointment of Trustees Act 1996, applications under Schedule 1 of the Children Act 1989, international children cases and child abduction cases.
He is regularly instructed in Children Act 1989 cases, and has conducted final hearings of significant length and complexity, appearing for the parents in High Cost Public Law cases where there have been findings of fact sought against alleged perpetrators of serious sexual abuse and/or violence. He has appeared alone against Alex Verdan K.C. of 4 Paper Buildings (Counsel to the film producer Guy Richie), Susan Grocott K.C. of Deans Court Chambers. He has particular experience of cases where one party has narcissistic personality disorder.
He has a particular interest in external and internal relocation cases, in particular to Scotland. In his last external relocation case, he successfully represented a mother seeking to relocate her child to Germany, where she wished to live with her new partner.
As a leading defence and prosecution junior he has conducted trials of length and complexity involving allegations of attempted murder and historical rape. Indeed, after leading one such rape case, off his own bat His Honour Judge Darling wrote a reference to the Crown Prosecution Service describing him as “an individual with Silk and Treasury Counsel written all over him”. Mr Vollenweider led his first case at the age of 31 years (7 years’ Call). He is now 46 years old and 22 years’ Call.
He has been a level 3 prosecutor, who has been instructed on Level 4 cases, and for over ten years was on the Attorney-General’s specialist panel of rape and child sexual abuse prosecutors. Now, he appears exclusively for the defence either as leading junior counsel or in privately paying cases. He has appeared in the Central Criminal Court (Old Bailey), Courts Martial (Germany), Divisional Court and Court of Appeal.
He has appeared in numerous applications under the Proceeds of Crime Act 2002 and has a keen interest in commercial fraud, having led two cases involving fraud and money laundering.
He can conduct private prosecutions and, indeed, has brought one such case against the Bank of Scotland Plc (Trading as Halifax) for the harassment of a debtor. The (then) fourth largest law firm, DLA Piper, represented the bank. As the case headed towards trial the bank wrote off the debt.
All areas, although the smallest part of Mr Vollenweider’s practice. He has a keen interest in international commercial arbitration and has been a member of Thomas More International in Mauritius. He appears regularly in the County and High Court and will undertake work such as Judicial Review and cases in the Judicial Committee of the Privy Council.
He has been involved in a civil case in the High Court seeking the restoration of a £250,000.00 AC Cobra to its rightful owner, where the other side had instructed leading Counsel.
He has particular experience of cases involving defamation of character, contracts, Torts (Interference with Goods) Act 1977, harassment, nuisance, personal injury including Fatal Accident Act 1976 claims and human rights.
He has been led by Silk in one such Judicial Review, involving human rights issues relating to the recovery of private costs in criminal cases, where the client had not applied for legal aid, as he had been deterred from applying for the same having been assessed as unsuitable for such by the on-line calculator. He had been acquitted and disallowed his some £70,000.00 worth of costs. Mr Vollenweider appeared without leading Counsel before Lord Justice Ryder sitting on the appeal from the Divisional Court. Mr Vollenweider abandoned the Silk’s points on appeal, preferring to rely upon his own new ground of appeal, which Lord Justice Ryder described as raising “…attractive issues that were not pursued before the Divisional court below….”
Mr Vollenweider has experience of the same, appearing for the partner of the deceased in a notable one involving Stepping Hill Hospital, where the hospital admitted liability after the inquest resulting in a substantial settlement for the partner.
He accepts instructions involving complicated matters at a very late stage.
He has an extension to his practising certificate, which allows him to conduct a case in a similar manner to a Solicitor, including the ability to instruct experts, barristers and to issue proceedings.
