Patrick O'Connor Q.C. practices in the broadest range of criminal and civil work. Whether it be at trial or on appeal, in high profile criminal or civil law, at an Inquest into a death in custody or a Public Inquiry, he brings his experience, his imaginative creativity and his commitment to bear for the benefit of the client. He welcomes direct public access work, in the same spirit.
