The disadvantage of the dual court system is that there are differences across the nation that imply distinct systems, and people can face biases and penalties for a violation or crime. The state law manages the power of state law, that is why the rulings about what is illegal or legal may differ according to the state. This contrast is especially prominent if the laws in the country differ. Another disadvantage of the American court system is that there is a set of prejudices and biases that can affect the trial. Authorities with different behavior, interests, and ideologies run the legal system, so the trials’ results might not be identical. In addition, the judges’ selection process also varies across the country. For example, in some states, judges can be elected instead of being appointed, which may affect their ruling and the outcome of the trial.
The advantage of the dual court system is that there is more than one court system, state and federal one, which is ready to protect people’s rights. This system allows the accused to appeal for assistance. If the innocent is charged, he or she has the right to seek support from alternate venues. This increases the probability of the individual to be heard.
Another advantage of the dual court system is that it acts according to the check and balance principle. It means that the Supreme Court has the power to limit the state and federal courts, which creates a balance in the system. If there is a conflict between state and federal courts, the Supreme Court takes precedence. Thus, the dual court system implies the separation of power and allows for securing political liberty.
