Comparative Law and Sociology Are Connected
When we compare legal systems, we’re not just looking at laws on paper—we’re also looking at how they function in society.
This approach (called functional comparative law) focuses on what laws do rather than just what they say.
Functional Comparison Is Used for Legal Reform
When people want to improve or unify laws across different places, they compare how laws actually work in real life.
This means figuring out which parts of a law are essential (important) and which parts are accidental (just specific to one country’s way of doing things).
It also means looking at the causes of legal differences and how they operate within society.
Functionalism Focuses on Real-Life Effects
Ralf Michaels says this approach doesn’t just compare legal rules; it looks at their real-world impact (what actually happens when the law is applied).
Instead of just analyzing legal theories, it studies events, results, and consequences.
Laws Are Tools for Society
Functionalism believes that laws are meant to solve social problems (this idea is called social engineering).
It uses functionality as a common basis for comparison (tertium comparationis) because laws in different places often aim to solve the same basic problems.
This method helps structure and organize legal comparisons in a way that makes sense.
Mark Tushnet’s Example: War and Emergencies
He explains that in constitutional law, functionalists study how different democratic nations make decisions about war or emergencies.
By comparing different systems, they can see which methods work better and which don’t.
Why Does This Matter?
It helps improve laws by learning from other countries.
It shows that laws need to be understood in their social context.
It provides a way to compare legal systems based on how well they function, not just how they’re written.
Basically, instead of just looking at laws like words on a page, functional comparative law studies how they actually work in real life to help solve problems in society.
