Answer: Only white European judges
Step-by-step explanation:
Colonisation of the Americas brought with it a hierarchical system where the Europeans placed themselves above all others and the British ranked very high in the European hierarchy.
One of the ways of preserving this system was to ensure that other races such as the Native Americans knew that they had no power over the whites. This was why a criminal case involving a British man was to be conducted under the authority of a white European judge regardless of where the crime may have been committed. The same was the case in Africa and Asia.
