In this lecture, Professor David Feldman argues that “constitutional politics are loose on a rough sea, with little navigational help”. He set out several factors contributing to these turbulent waters: challenges to the rule of law; persistent questions over the relationship between the Prime Minister and the Cabinet; and tensions in the Union regarding devolution. Whilst this may mean that the UK is facing a constitutional existential crisis, Professor Feldman stated that it is important to recognise that such crises are nothing new. However, the particular danger of the current crisis was a lack of awareness and understanding of key constitutional principles that are needed both to constrain governmental actions and provide sufficient flexibility to weather the inevitable storms. If we are to navigate these white waters effectively, Professor Feldman argues that there is a need for consistency in our understanding of these constitutional principles in the Supreme Court, alongside knowledge and acceptance of these constitutional principles amongst MPs and Ministers. We can think of no-one better than Professor Feldman to provide this knowledge.
