Burmah Oil Co. v Lord Advocate was an important legal case that happened in the United Kingdom in 1965. In this case, the Burmah Oil Company (a large oil company) sued the Lord Advocate (the highest legal officer in Scotland). They were suing because the Lord Advocate had said that they had broken the law.
This case was important because it helped determine how governments should treat large companies. The court said that when a government makes a law, large companies must be treated fairly, just like everyone else.
