Dignity 4 Patients says it will not give up in its pursuit of justice against disgraced Doctor Michael Shine.
89-year old Dr Shine, who worked in Our Lady of Lourdes Hospital in Drogheda, was released from jail earlier this year after serving three years for indecent and sexual assault of young boys.
The DPP has decided not to prosecute a further 25 case complaints made to Gardaí relating to the shamed Doctor.
Dignity 4 Patients says the reasons given for not proceeding with the additional prosecutions don't make sense.
