(a) His Honour made an error of legal principle by failing properly to apply the relevant parts of Court Procedures Rules 2006 (ACT) to the plaintiff's application on 24 November 2010 in conformity with the requirements of r21 of the Court Procedures Rules 2006 (ACT).
(b) His Honour failed properly to direct himself as to the operation of r21 of the Court Procedures Rules 2006 (ACT).
(c) His Honour failed to take into account or gave insufficient weight to the relevant consideration of the timely disposal of the proceedings, and all other proceedings in the Court, at a cost affordable by the respective parties.
(d) His Honour took into account an irrelevant consideration in purporting to apply case management principles pursuant to r21 of the Court Procedure Rules 2006 (ACT) by characterising a building case between corporations and a defamation action as being classes of proceedings which are subject to different case management principles.
(e) His Honour failed to take into account or gave insufficient weight to the relevant consideration raised by the plaintiff, being the costs and the commercial burden occasioned to it by the defendant's ongoing delay in the conduct of the proceedings.
(f) His Honour failed to take into account or gave insufficient weight to the relevant consideration that the defendant had been ordered to give security for the plaintiff's costs pursuant to r1900 of the Court Procedure Rules 2006 (ACT) and/or pursuant to s1335 of the Corporations Act 2001 (Cth).
(g) His Honour failed to expose his reasons for disposing of the plaintiff's application made on 24 November 2010 in finding that it was reasonable to allow the defendant a further two months to prepare a further amended defence and counterclaim, notwithstanding the history of, and his Honour's findings in, the proceedings.
(h) His Honour arrived at a result so unreasonable or unjust as to suggest that one or more of the foregoing errors had occurred, even though the error in question did not explicitly appear on the face of the reasoning.
