That art is appellate lawyer jargon for the techniques used to convince the Powers That Be to reverse a long-established precedent.

1. The old precedent has been overturned in related areas by recent transformations (your Point A).

2. Overturning the old precedent in those related areas has caused changes in the subject area, requiring transformations there which cannot be accommodated by the old precedent (your point B).

3. A positive value will result from the new precedent, which is not and cannot be realized under the old precedent (your point C); and BTW, since I wrote the main brief, changes make it even more crucial to adopt the new precedent (the PS to your point C).

Great advocacy technique.

At which point, your bean-counter opponent will say.

"Now, we're paying for 1 LT per platoon. This lunatic wants us to pay for 1 CPT and 2 LTs per platoon - with corresponding increases in NCO costs."

"And, BTW, if we use our funds there, we will have to cut appropriations for the SuperDooper 3000XBQ Project, which will give us a single vehicle to be used for all conceivable land, sea (surface & below) and air operations - and even allow us to attack the Martians - and can be run completely from the SuperDooper 4000GFZ computer right over there - which can even think for itself."
To paraphrase one of my law profs: "Courts often miss the obviously correct and logical answer because of trained indifference."
