Following a law change from bill to enforcement
A passed bill is rarely the day anything changes. How to tell what has actually taken effect.
Passing is not the same as in force
A cannabis bill may pass a legislature, be signed, and still change nothing for months. The law usually has a commencement date, and rules for licensing, labelling and sales are often written afterward by a regulator. Each step has its own date and its own document.
The usual stages
- Proposal: a bill or initiative is introduced or qualifies for a vote.
- Passage: a legislature votes or the public does.
- Signature or assent: the head of state or government signs it into law.
- Regulations: a regulator writes the detailed rules, often with a public consultation.
- Commencement: the date the rules apply.
- Licensing and enforcement: the first licences are issued, and inspections begin.
How to check what is in force
- Read the commencement section of the law itself.
- Look for the regulator's own notice that rules have started.
- Look for amendments: a law can be changed after it starts.
Headlines versus documents
News coverage often reports the vote and not the start date. Treat a headline as a prompt to find the document, and trust the document.
