• Authoritative works - Books written by constitutional experts, e.g., Waller Bagshot or Erskine May

Authoritative works are not legally binding, they are not enforceable, they serve as guidance

• Codified constitution - A constitution written in one document, e.g., USA
• Common law (president) - Laws made by judges in court rulings ,e.g., Greta Miller case
• Constitutional sovereignty - The concept that the constitution is the highest law also known as fundamental law
• Conventions - A norm or tradition, e.g., loss of no confidence vote triggers UK election
• Entrenched - Requiring super majority to amend
• Fundamental law - Constitutional law that all other laws comply with
• Parliamentary sovereignty - Three principles Parliament is the supreme law maker
• Royal prerogative - powers inherited by the PM in the name of the monarch
• Rule of law - A concept that suggests that no-one, including the government, is above the law
• Separation of powers - The different branches of government have entirely different powers and people
• Statute law - Law that has been passed by Parliament and written into Acts of Parliament
• Supreme court - The highest court in the UK, sets a lot of common law/- president
• Uncodified constitution - A constitution is more than one document, some parts may be unwritten, e.g., - UK

Since parliament is the supreme law maker, we do not have fundamental laws. Central government holds sovereignty and can devolve/absorb power
