"I honestly can’t thank Joana enough for everything she has done for me. From day one, she was professional, reassuring, and completely committed to my case. Throughout one of the most difficult times in my life, Joana stood by me with compassion and strength, always keeping me informed and calm, even when I was overwhelmed. Thanks to her hard work, my case was dropped, and I can now move forward with my life. If you want someone who truly cares and will fight for you with everything they’ve got, Joana is that person. I couldn’t have asked for a better solicitor."

"My experience with JMW has been wonderful in particular the solicitor that was appointed to deal with my case; Joana Santos. Joana was extremely kind and professional. I felt she had my best interest at heart. She was always prompt in responding back which is paramount in my case because of so many uncertainties involved. Joana is someone that I won’t forget in a lifetime and I highly recommend her!!"

"Excellent firm! I highly recommend. Special Thanks to Joana Santos that looked after my case from beginning to end professionally."

• R v LM – successfully defended client charged with Section 20 grievous bodily harm arising from use of taser during the arrest of a burglary suspect, following a foot chase in the early hours of the morning. The complainant fell from height during the incident and suffered tetraplegia as a secondary injury. The trial involved detailed consideration of body-worn footage, eyewitness accounts, and expert evidence on tasers and their use, which led him to be acquitted. This case was subject to national media interest.
• R v JR – successfully defended client charged with possession of ammunition.
• R v TC – successfully opposed a Domestic Violence Protection Notice (‘DVPO’) following strong written representations served arguing that the threshold was not met and there was no clear evidence to suggest that the client presented a continuing risk nor that the complainant required protection. It was further argued that the client was entitled to the presumption of innocence, and imposing a DVPO in the absence of formal decisions or charges undermines due process. Therefore, evident that the evidential threshold required, even on the balance of probabilities, was not satisfied.
• R v MS – the client had accumulated 12 points on his driving licence, and at risk of disqualification under the totting up provisions. A skeleton argument was drafted and a comprehensive mitigation bundle put together ahead of the hearing to demonstrate exceptional hardship. Counsel was instructed for the hearing, and the Court agreed to allow exceptional hardship in his case.
• MPS v L – case not proved following a five-day police misconduct hearing into allegations of sexual assault and harassment made by a fellow officer, the Panel rejected the IOPC’s case in its entirety.
• MPS v A – case withdrawn following allegations of sexual assault. The defence expert was instructed and opined that the description of the events was in keeping with NREM parasomnia (sexsomnia/sleep sex) rather than sexual assault. The Appropriate Authorities withdraw their case in its entirety.
