As I was saying, it seems to me that there is a contradiction. Paragraph (b) refers to section 745 and says it is optional. The length of time referred to in section 745 is 25 years. However, paragraph (b) refers to section 745, but at the same time it says that the judge may decide the length.
There may not be any problems. As I said, I'm no drafter, but it's something that leaps to the eye on the face of it, as I said in English.
