The Attorney-General's Chambers (AGC) will on Tuesday seek the High Court's permission to launch a contempt of court action against blogger Alex Au Wai Pang.

The AGC has accused the 61-year-old blogger, who runs sociopolitical blog Yawning Bread, of having "scandalised the judiciary" of Singapore in two articles he published in October.

They are: "377 Wheels Come Off Supreme Court's Best-Laid Plans", which was published on Oct 5, and "Church Sacks Employee And Sues Government - On One Ground Right, On Another Ground Wrong", which was published on Oct 12.

In the Oct 5 post, Mr Au is said to have accused the Supreme Court of "deliberately manipulating hearing dates", while in the Oct 12 post, he is said to have alleged that the judiciary was incompetent of making independent judgments.

Mr Au was let off with a warning by the AGC for a separate contempt of court offence in July last year after he withdrew an article and issued a public apology.

He is not required to be in court for the leave hearing on Tuesday, in which the judge will assess if there is sufficient basis for a case against Mr Au, or whether the application should be dismissed.

But if permission is granted for the AGC to proceed further, it does not mean that Mr Au is guilty of contempt. In that event, court papers will be served on Mr Au, who will be entitled to a full hearing for the court to determine the matter.
