Judicial Review and Courts Bill

I am grateful to the Lord Chancellor for giving way. I would like to intervene later on the specifics of this matter, but may I start by asking him this: the right to judicial review in Scotland is protected by article 19 of the Treaty of Union and it is a devolved matter under the Scotland Act 2016. His predecessor gave me a written assurance that the focus of this Bill would be on UK powers and procedures relevant only to the jurisdiction of England and Wales. Will he tell my why that promise has been broken?
