Even after departments were asked for information, summonsing departments was undertaken by the PSC. Despite the constitutional responsibilities of the PSC and the legislative responsibility of government departments to assist the PSC in executing its responsibilities, some departments did not form part of the study due to late or non-submission of the requested information. The KwaZulu-Natal Department of Housing, the Western Cape Department of Public Works and the Eastern Cape Department of Housing did not supply the requested documentation. The National Department of Public Works only provided documents after the study was concluded, and thus could not be included in the evaluation.
