Final answer:
Courts shape public policy through their decisions and opinions. They interpret the law, set precedents, and have an impact on elections and other policies. They can also be influenced by public opinion and external factors.
Step-by-step explanation:
When it comes to shaping public policy, courts play a significant role through their decisions and the opinions expressed by judges. Courts interpret the Constitution and laws and set precedents, which in turn influence public policy. For example, the Supreme Court's decision to establish the 'one person, one vote' standard in 1962 impacted elections. Additionally, courts can be influenced by public opinion and external factors. Their interpretation of the law can evolve as societal views change.
