List 98 is not a list maintained by the Department for Education and Skills. Some educational establishments and authorities have introduced and maintained such lists under local arrangements, but they are not a requirement under education or employment law.
Requests from courts for information about people giving evidence who are on List 99 are not received routinely. Any request or order by a court, or for the purpose of court proceedings, would be considered in accordance with the law on a case by case basis.
