Legal 500 Editorial commentary

Testimonials

Collated independently by Legal 500 research team.

  • ‘The Matheson team has been very supportive in a claim situation our company had in Ireland. Several times their prompt assistance and advices were needed at short notice and the Matheson team always supported us in a timely matter in this true Tier 1 practice.’

  • ‘Nicola Dunleavy, Senior Partner, is extremely competent and I have personally worked with her since 2016 and always received the best support, although team members reporting to her have done much of the ground works the last years. However, as soon as presence in customer negotiation meetings are needed, she has always been present in person.'

  • 'Ruadhán Kenny has been very involved the last 6 years and always gives full attention and excellent support.'
  • ‘Matheson have a highly effective and skilled Dispute Resolution team, who are able to astutely assess the art of the possible in respect of any litigation, whether the client is a potential or actual plaintiff, or defendant, as the case may be. In respect of a very important High Court action that the Dispute Resolution team took on our behalf against the FSPO, the team's view of matters was invariably proven to be correct at each given stage of the litigation, even when the matter was appealed to the Court of Appeal by the FSPO.'

  • 'The team provided authoritative, readily-understandable advice, which inspired confidence in our company and reassurance in respect of our decision to commence proceedings against the State, a decision made further to Matheson's advice, and one which was subsequently vindicated when we successfully defended the FSPO's appeal in the Court of Appeal.'

  • ‘I have dealt with April McClements and her team in respect of several litigations and highly sensitive disputes. April is able to read a litigation in a highly astute way, instilling confidence in her client's decision to commence proceedings. April is a very friendly and engaging lawyer, who manages a given litigation from start to finish in a highly professional manner. April is not afraid to call out weaknesses that she may identify in a given case, but is able to adapt and plan for these so as to secure the likely success of the litigation as a whole, on the assumption that any such weaknesses are not fatal to the case.'

  • 'Karen Reynolds and her team have been supporting us through a particularly sensitive and bitterly-contested dispute, that we have been pulled into (through no fault of our own) between two third parties. Karen stepped into the breach on this one, and was able to cut through the "white noise" and ascertain exactly what was going in a calm and professional manner, all whilst taking a firm and no-nonsense approach to engagements with the third parties' solicitors, in what must have been a very trying dispute to "unwind". We are now approaching the "endgame" with a successful resolution in sight. Karen is a very effective litigator who can be relied upon to comprehensively and resolutely safeguard her client's interests.’
  • ‘For me, Connor Cassidy has been a standout individual. Very consistent and reliable. I have learned from him and his decisions around our cases. We know he is supported in the background by Julie Murphy O'Connor and are very grateful for that knowledge on our side.’
