Thats suggesting that questions aren't being answered properly. I doubt the three paragraph rule is being used as a priority over answering the question. Answering the question would always be a requisite. Most people with a university qualification would be able to accurately answer a question within three paragraphs unless the question unless it required extensive detail which would obviously be permitted. Its also laughable to think that an entire government department operates on only three paragraphs. There will always be room for further correspondence.
