Someone with authority can do anything that wished?

If someone in an organization with authority is it suppose can do anything that they wish to? No need to follow rules and procedures? I found that something happened last nite which not sure whether is it true. Saw someone doing a class which I don't think he did the training. Where knowing someone else is available and qualify to do the class and yet for this person to do it. What I'm thinking is what for is the training? If no training also can do what we've gone thru useless? In this case, any cats and dogs also can do. What is this about?
