* **Reflect society’s values**
If a law’s in line with society’s current values, then people are more likely to follow that law than disregard it. Therefore, laws need to change when society’s values change
\
* **Be enforceable**
If people break the law, there must be punishments involved, it must be possible to catch them or sue them. If a law has no punishments/is not enforced people are less likely to abide by the laws.
\
* **Be known**
An effective law must be known, if people don’t know about the law, then they can’t follow it.
This goes both ways, it’s an individual’s responsibility to find out what the law is in a situation that affects them. However, law-makers also need to keep the public informed of any new laws being passed by parliament.
\n
* **Be clear and understood**
Laws must also be clear and understood in order to be effective, they should be written in a way so that anybody can understand it, and the intent of the law is clear. If laws were unclear or written in a language that nobody understood full of gibberish, then people won’t follow the laws.
\
* **Be stable**
If laws were constantly changing, then no one would ever be 100% certain on what the law is, resulting in the law becoming ineffective as people would not be able to follow the correct law. If a law has remained constant over a long period of time, then people are more likely to follow the law as the details have remained unchanged.
