88.Section 35 allows the Welsh Ministers to vary or remove existing conditions, or add new conditions, to a person’s registration with immediate effect where they have reasonable cause to believe that there is a risk of significant harm to a child if they do not do so. The Welsh Minsters must take such action by written notice to be served on the registered person by delivering it to them or by sending it by post to that person’s last known address. The notice must include the Welsh Ministers’ reasons for believing that a child is at risk of significant harm, specify the condition varied, removed or imposed and explain the right of appeal to the First-tier Tribunal under section 37.
