This report on the inspection of Cloverhill Prison identifies a number of such systemic issues. Chief amongst these is the scourge of overcrowding and the ongoing scandal of people living in prison being obliged to sleep on mattresses on the floor, in close proximity to un-partitioned toilets. Other recurring themes include shortcomings in record keeping, the absence of administrative support for Chief Officers and Chief Nurse Officers, an ineffective complaints system and unduly limited telephone contact with the outside world. The report also addresses the persistent presence in prisons of people with acute mental health conditions. The commissioning of new male prison in Limerick has recently provided an additional 90 spaces and the female prison accommodation in Limerick Prison will provide 22 additional female cell spaces when it opens in July. In addition, the refurbishment of the Training Unit in Mountjoy last year provided an additional 96 spaces. In respect of Cloverhill Prison the F Block has recently opened to specifically alleviate the overcrowding issue in this location and there are currently 23 prisoners housed in this Block. The need to ensure the continued availability of modern prison facilities with adequate capacity will continue to be central to the work of the Irish Prison Service and will be core to the development of the new Irish Prison Service Capital Plan. The Irish Prison Service intends to seek funding as part of the 2024 Estimates Process for [...]
