A computer-generated image of the planned development in Dundrum, which is facing a second legal challenge from developer Mark LeonardThe development of almost 1,000 homes on the site of the former Central Mental Hospital in Dundrum, south Dublin, first planned five years ago, has been hit with a fresh legal challenge. Leonard took judicial review proceedings against this decision, arguing that the development was in conflict with the Dún Laoghaire-Rathdown County Development Plan. The board conceded the legal challenge in April 2024, but the LDA, which was a notice party, decided to continue to defend the case. The SHD system has been scrapped, but the judicial review proceedings are ongoing. We can start on this next month and even if we do get a judicial review, we’re going to start next month.
