Most constitutions are codified, but obvious examples are USA, France, Germany (basic law)
Un codified (unwritten)
Eg UK, NZ, Israel
Don't use "unwritten" since many aspects are written, or appear in law.
UK is a "constitutional monarchy" where the "sovereign reigns but does not rule" unlike, say, Arab monarchies.
Absolutist constitutions
Rulers are "above the law"
Authority to produce and change legal norms are centralised and absolute to the ruler
Legislative supremacy constitution
Crucial norm of "legislative sovereignty"
Constitution is flexible or not entrenched. Can be amended in the same way that ordinary legislation is passed
Examples are UK, NZ
Parliament is sovereign and whatever it passes is law until amended or repealed by same body. No special procedures for amending a constitution, just done through parliamentary legislation.
No bill of rights, explicit rights can only be enshrined in legislation BUT in e.g. UK you have a right to do something until it is forbidden not other way around.
"higher law" (rigid) constitutions
Institutionsof the upstate are established by and derive authority from a written constitution
Ultimate power to the people through election
Public authority is lawful only insofar as it conforms with the constitutional law
Constitution provides for a bill of rights and constitutional justice to defend those rights
The constitution itself specifies how it may be revised.
In theory this makes it far more difficult to change. In practice activist judiciary and finding ways round things (full faith and credit), posse commitatus, and other "holes" in the constitution allow govt to do things without amendment.
Bills of Rights
Impose substantive constraints on exercise of public authority
Public authorities must act in accordance or their acts will be red illegal
Negative rights vs positive rights
Negative: state cannot stop you doing these things
US mainly negative rights
Positive: imposes duties on governments to facilitate enjoyment of a particular right
But also therefore imposes an obligation on "victims" of the state as payers
E.g. Mexico imposes employment rights and so on
South Africa
Judicial review and constitutional courts
By and large with a codified constitution you would need to have something to review decisions to see whether they are compatible with constitution
Main types a judicial review and constitutional court
Judicial review is like the US Supreme Court
SCOTUS system is simply the "highest court" in the entire federal system.
It hears ordinary cases as well as constitutional chalenges
Constitutional challenges must be part of a real case - "concrete" not "abstract". Ordinary judges recognise a constitutional issue in a lower court case and refer it up.
"European" system tends to be "constitutional court"
Not any old judge can make a ruling on constitutional conformity. A centralised specialised constitutional court is established and it only does this. Possibly a better division of powers than with e.g. SCOTUS
Constitutionalcourt often does not need a case - it looks at laws or decisions in abstract. They can "call in" legislation. SCOTUS is always done by hearing a particular case.
SCOTUS members appointed for life. Constitutional courts tend to appoint for specific terms.
