Another issue: Laws can be against the constitution.
2 different systems in world:
1. Constitutional supremacy (US/Germany/France)
Constitutional court decides if laws are in line with constitution
(f.e.: US: abortion laws were against constitution)
If not: then law is not valid anymore
2. Psovereignty (Netherlands)
When making a law, parliament checks if laws are in line with constitution
Courts cannot decide upon this.
