same thing if I'm talking about a piece of legislation
I would reference Section 42 subsection 3 point 4 for someone I'm training
if I'm talking to someone in the business it would be 42, sub 3, point 4
In British legal terminology, Acts of Parliament are split like this: Each distinct "enactment" within an Act of Parliament is called a section (abbreviated "s.", plural "ss."). Each section has a distinct number, in continual sequence from "s. 1" (section one) onwards. If a section is subdivided or has subordinate elements, then these are known as subsections, each of which has a bracketed number; e.g., "s. 1(4)" is subsection 4 of section 1. Subsections are subdivided in turn into paragraphs, which are identified by an italicised letter; e.g., "s. 1(4)(c)". Subparagraphs are identified with lower-case Roman numerals; e.g., "s. 1(4)(c)(viii)".
That would be spoken as "section one, subsection four, paragraph cee, subparagraph eight".
