Law in a Time of Crisis by Jonathan Sumption. If you don’t know who he is, you really must find out forthwith. He has attracted a band of rather silly YouTube fans but he is very thoughtful and interesting to listen to.
The book is a set of slightly edited talks he has given over the years, including one on COVID-19.
The titles of the pieces are:
The Historian as Judge
On Apologising for History
Magna Carta Then and Now
Arcana Imperii: State Secrets through the Ages
The Disunited Kingdom: England, Ireland and Scotland
Home Truths about Judicial Diversity
Abolishing Personal Injuries Law - A Project
A Question of Taste: The Supreme Court and the Interpretation of Contracts
Brexit: A Primer for Foreigners
Brexit and the British Constitution
Britain in the Twenties: The Future of the Constitution
Government by Decree: COVID-19 and the British Constitution
