Imagine if the only way to get a court to hear your plea were to file the correct form of action. Depending on what you want the court to do, you might have to file a different form, and you also have to know which court to petition. As you probably know, courts following the English law tradition have simplified their forms of action (say, [0]) so that this task is much easier now than it used to be.

A common problem with this sort of program is that the bureaucratic requirements end up preventing people from successfully applying or completing paperwork which they didn't know that they needed to handle. While this might seem like a mere UX problem to you, or perhaps "a formality", I assure you that it can and does drive people mad. [1]
