The memorandum to which the Deputy refers was issued in 1979 by the then secretary of the Department of Education and sought to reassure some teachers in community and comprehensive schools that they would enjoy the same rights as regards disciplinary matters as teachers employed by vocational education committees. However, as regards a sworn inquiry specific statutory powers are required before such an inquiry could be held. Teachers under vocational education committees are, as officers of vocational education committees, specifically covered by the vocational education Acts. Community and Comprehensive school teachers are not. In the absence of statutory powers, I cannot establish an inquiry as requested which would take evidence on oath and compel witnesses to attend. Any attempt on my part to do so would be ultra vires.
