Bureaucracy means a large group of people involved in running a government.
Bureaucratic control means the power of the public services or public branches to implement rules over the public in the services they render. For example, the NFA of the National Food Authority, they render services to the public like the NFA rice they sell at a low cost price. When we talk about bureaucratic power they have, they can change the price of the rice they are selling to parallel the price of commercial rice, that's their power. And the only way the public can protest against it is a battle in the Court of Justice. Gets? :)
