We have extensive experience adivising and representing clients through all stages of complex and high-value criminal proceedings.

Many clients instruct our firm for our expertise in guiding them through the early stages of an investigation (and preventing charges being brought at all) and many instruct us for our tenacity in defending them throughout lengthy trials.

We interrogate the merits of each case, putting together the right partner-led team with the correct expertise to secure the best outcome possible for each client. Fraud allegations often have international elements and our experience in multi-jurisdictional prosecutions throughout the globe, as well as the contacts we have developed over the years, prove invaluable in the complex and high-value instructions that PCB Byrne specialises in.
