The pertinent question is "were they given a fair trial"

Some of the people conducting the trials has also been involved in suppressing the rising. This I believe is prohibited in the military manual.

So question 1. Is it prohibited in the Military Manual that an officer involved in an action cannot take part is any later legal proceedings. A simple yes or no answer will suffice.

So question 2. If the answer to question 1 is yes then should these people have been debarred from being involved in the trials. A simple yes or no answer will suffice.

General Maxwell took it upon himself to conduct the trials in secret and without a defence being allowed.

So question 2. Was this ruled illegal by Crown Law Officers, again a simple yes or no answer will suffice.
