A High Court judge will consider whether it was unlawful to order dementia sufferer Lord Janner to appear in court in person to face child sex charges.
Lawyers acting for the former Labour peer and MP told Westminster Magistrates' Court in London that their application has been listed "urgently" before a judge and is likely to be heard either tomorrow or Thursday.
Senior District Judge Howard Riddle, the chief magistrate, ruled last week that Janner must attend the magistrates' court on Friday to face 22 charges spanning a period from the 1960s to the 1980s.
Janner, 87, did not have to attend today's hearing. Last Friday his lawyers said he was too ill to attend the court for a first hearing in the case and argued he may suffer a "catastrophic reaction" if made to appear in future.
