This is how it was first drafted. Then we sent it to the drafter and the drafter came back and said, you have to say paragraph (c.1) as a technique. Paragraph (d) will always be the last one. As a technique, you don't renumber the last paragraph; you just intercede them with it.
For example, if you were to add another paragraph after (c.1), it would be (c.2). You don't just change the number of the paragraphs. That's the principle that was explained.
