Brother Tobin is the first Christian Brother in Ireland to be imprisoned for the sexual abuse of institutionalised children. It is understood that 11 other files were sent to the DPP following the Garda investigation into Letterfrack which began in 1999 and concluded in 2001.
It is expected that more Christian Brothers from Letterfrack will come before the courts.
In a statement last night, the Christian Brothers sincerely apologised to victims of Brother Tobin.
It read: "The Christian Brothers deeply regret the hurt and pain caused to those who were abused by Brother Maurice Tobin. We are greatly saddened by his actions and offer our sincere apologies to those who were abused and to their families.
"We recognise the trauma and distress that they have suffered and the betrayal of trust involved. The Christian Brothers pledge to continue to work towards healing and reconciliation."
Brother Tobin was led away in handcuffs by prison officers after Judge Harvey Kenny passed sentence. One man ran after him and shouted "Pig".
The other victims showed greater restraint. They congregated outside the courthouse eager to tell their stories.
"It will never end for me," one victim said. "I'll carry this with me to my grave."
Wearing a grey suit and blue shirt and tie, the accused had sat motionless to one side of the courtroom, accompanied by a Garda detective, only raising his eyes to look at each of his victims as they took the stand to give evidence of the impact his abuse had on their lives.
Mr Jim Lyons, who is now 52, told the court the pain would never leave him.
"I will have to live with it for the rest of my life. I was abused by him when I was 14, and I have never forgotten. I'm receiving counselling at present."
Mr Frank Shanley said he was aged 11 when he was abused. He said he had been taken from his mother because she could not look after him.
"Nobody was there for us. Nobody was there to fight for us. I tried to let my mother know what was happening to me but she wouldn't listen.
"I contemplated suicide each time I knew I had to go back to Letterfrack after holidays at home.
"I hate that man," Mr Shanley said of his abuser.
Another victim told the court: "We never had enough to eat. We were always hungry".
