A challenge to the country's level 4 Covid-19 lockdown is heading to the Court of Appeal.
Lawyer Andrew Borrowdale had argued in the High Court that the Director-General of Health went beyond his powers when he put the country into lockdown in March.
Last month, the High Court ruled that in the nine days from 26 March, the requirement for people to stay at home was justified but unlawful.
Dr Borrowdale now says he is appealing to the Court of Appeal.
He said the High Court judgement raises vital issues about human rights and constitutional law, which should be assessed by a senior court.
