Greens say Macdonald should produce documents

THERE have been calls for disgraced former Labor Minister Ian Macdonald to front an Upper House inquiry over his part in a major mining scandal being investigated by the state's corruption watchdog.

NSW Greens MP Jeremy Buckingham says Mr Macdonald should be forced to produce documents relating to the granting of coal exploration licences which allegedly benefited former Labor powerbroker Eddie Obeid's family.

During an inquiry into the claims late last year, the Independent Commission Against Corruption heard current Liberal Roads Minister Duncan Gay had called on Mr Macdonald to produce the documents in parliament three years ago.

Mr Buckingham said Mr Macdonald's actions were "negligent at best and a cover-up at worst" and he should be forced to explain his failure to produce the documents in NSW Parliament.

Mr Macdonald told the ABC the calls were "a bit of a fishing exercise for the Greens" and that he was "pretty sure the department has conducted this in an appropriate way".
