I am learning about US legal system. It means that I am trying to understand the legal landscape which is defined by the characteristics that arise throughout every aspect of American jurisprudence. The U.S. legal system is extremely complicated when government is shared between local, state, and federal governments.

Objectives: -types of legal case -the legal system structure - steps of a lawsuit

Can you help me to understand and catch the main concepts of the following questions?

Q1: Can you compare the US legal system with the UK or Australian legal system? What are the main differences and pro and cons of their legal systems? Please try to explain it in the case example.

Please attach your case or example's reference's URL link, I will read more details later.
