The family of jailed politician Eddie Obeid has failed in its legal battle to suppress parts of a Federal Court judgment.

The Australian Competition and Consumer Commission launched legal action in 2015 against two of Obeid's sons, Moses and Paul, along with prominent lawyer and businessman John McGuigan, his son James and investment banker Richard Poole as well as companies associated with them.

The ACCC alleged the group had engaged in cartel conduct and that in 2009 Paul and Moses Obeid struck a deal with Cascade Coal that resulted in other bids being withdrawn to ensure Cascade was awarded a lucrative coal exploration licence from the NSW government.

In July Federal Court judge Lindsay Foster found in favour of the Obeids and the other defendants. However, Moses Obeid took action to have parts of Justice Foster’s 172-page judgment suppressed.
