“It is repugnant to the proper administration of justice that a contemnor can flout orders of the court then absent himself from the committal hearing, then avoid serving whatever prison sentence is imposed and then finally avail himself of the procedures of the Court of Appeal, whilst enjoying the shelter of some safe haven overseas…it may be thought that persons committed to prison for contempt should only be entitled to appeal with permission…I would suggest that at the very least there should be a permission requirement in case where the appellant has refused to submit to the jurisdiction of the court.”
