Former NSW Labor ministers Ian Macdonald and Eddie Obeid, and the latter's son, Moses, will face a long trial in 2019 over the granting of a multi-million dollar coal mining exploration licence.
The trio pleaded not guilty on Friday in the NSW Supreme Court to conspiring for then-minister Macdonald to grant the licence "without impartiality" on Obeid family land at Mount Penny in the Bylong Valley near Mudgee between September 2007 and January 2009.
In 2013, the Independent Commission Against Corruption found the licence enabled the Obeid family to make $30 million.
Moses Obeid, who is on bail, appeared in court in person while his father and Macdonald appeared via video link.
Eddie Obeid was jailed for at least three years in December after being found guilty of misconduct in public office in 2007 over lease renewals for two lucrative Circular Quay businesses that he and his family had a financial interest in.
Macdonald is serving a maximum 10-year sentence for wilful misconduct in public office.
The trio's estimated 23-week trial, during which the Crown is expected to call 44 witnesses, was set down for March 4, 2019, by Justice Peter Johnson.
