Key legal question
Whether security detention could be ordered at the appeal stage without first hearing and producing the absent defendant.
Extracted holding
Yes. In this procedural setting, the appellate court may, by analogy to the Criminal Procedure Code, order security detention together with the appeal judgment even if the convicted person failed to appear unexcused.
Extracted reasoning
The defendant was summoned to the appeal hearing and could have been heard there. By staying away without excuse, he could not prevent a detention order. After arrest, he may request release.
