Candidates who are successful in open competition receive a starting salary equal to the minimum of the incremental pay scale in question, irrespective of whether they are already working in the Civil Service or working in outside employment. However, both categories of candidate may, in certain circumstances, receive a starting salary which exceeds the minimum of the pay scale in question. In the case of an existing civil servant, starting pay may be set at existing pay plus an accrued increment, that portion of the current increment which has been earned by or has been accrued by the officer, if such a level of remuneration is more favourable than the minimum of the grade to which the individual is being appointed. This affords a significant protection to the candidate who is already a civil servant in that it at least preserves his-her existing level of remuneration in all circumstances.
