A well-written submission, a logically built-up argument is easier for a judge to understand.
The judge is more likely to pick up counsel's line of argument and, hopefully, its submission. Uniformly used editing rules make it easier for a judge to find the documents, referred to in the Memorials and it will be easier for him or her to read through the document in general. A well written and neatly and uniformly presented document will show the judge that effort is being put into the case. Combine that with excellent legal arguments and most judges will at least be willing to listen to your case with an open mind.
In the attached document you will find a brief explanation to writing a memorial.
