THE government has rejected an opposition call for a full judicial inquiry into $18 billion of its economic stimulus measures, including the halted home insulation scheme and the school building program.In announcing his call for the judicial inquiry yesterday, the Opposition Leader, Tony Abbott, said there was a ”significant and growing level” of taxpayer concern about reported waste in the school building and insulation programs.Mr Abbott said in a later letter to the Prime Minister, Kevin Rudd, that both programs had been ”poorly designed in haste and have been badly administered”.Mr Abbott added the scale of reported ”waste and mismanagement” in both programs raised questions about the competence of the government to deliver programs and a full judicial inquiry was necessary to restore public confidence.”Any failure to do so can only be interpreted as an admission that you have something to hide,” Mr Abbott wrote.He said the inquiry should be established immediately and be required to report by the time parliament resumed in August.But a spokesman for the Prime Minister ruled out an inquiry, saying the Auditor-General was already investigating the insulation and school building programs.A spokeswoman for the Education Minister, Julia Gillard, said Mr Abbott’s demand for a judicial inquiry was ”nothing more than another excuse for Mr Abbott to cut funding to schools”.”His daily criticism of a program that is delivering new facilities to every school means he will have no choice but to cancel projects if elected,” Ms Gillard’s spokeswoman said.
