NUMBERING

In regulations, sections are numbered using consecutive Arabic numerals in boldface that are followed by a period, except when the section number already contains a period, for example 3.1. When a regulation contains two or more parts, divisions or subdivisions, the numbering of sections does not begin again at "1" but follows the last number in the previous part, division or subdivision. The other provisions are numbered or lettered as follows:

• Subsections are indicated by using Arabic numerals in parentheses.
• Paragraphs are indicated by using italicized lower-case letters in parentheses.
• Subparagraphsare indicated by using lower-case Roman numerals in parentheses.
• Clauses are indicated by using upper-case letters in parentheses.
• Subclauses are indicated by using upper-case Roman numerals in parentheses.
• Sub-subclauses are indicated by using Arabic numerals.

Example:

•   1. (1) … .
• (2) … :
  • (a) … ;
  • (b) … :
    • (i) … ,
    • (ii) … :
      • (A) … ,
      • (B) … :
        • (I) … ,
        • (II) … :
          • 1 … ,
          • 2 … ,
        • (III) … ,
      • (C) … ,
    • (iii) … ,
  • (c) … .
• (3) … .
•   (2. … .

The provisions of a regulation should not be renumbered when the regulation is amended because there may be too many cross-references in that regulation or in other regulations or orders. Renumbering could create confusion as to which provision is intended by the reference.

A decimal numbering system is used when new sections, subsections, paragraphs, etc. are added to a regulation. Subsections inserted between subsections (4) and (5) would be numbered (4.1), (4.2), (4.3), etc. Paragraphs inserted between paragraphs (b) and (c) would be designated (b.1), (b.2), etc. To insert a section before section 1, it is necessary to add the new provision before section 1 and then renumber section 1 as 1.1. However, it is possible to insert a (0.1) subsection before subsection (1).

The following are examples using the decimal numbering system:

To add more than 9 sections between sections 5 and 6:

•   5.
• 5.01
• 5.02
• […]
• 5.1
• 5.11
• 5.12
• […]
•   6.

Or

•   5.
• 5.1
• 5.11
• 5.12
• […]
• 5.19
• 5.2
• 5.21
• 5.22
• […]
•   6.0

Note: Although zero is not inserted after 5.1, that number represents 5.10.

To add sections between sections 3.1 and 3.2:

•   3.
• 3.1
• --- 3.11
• --- 3.12
• 3.2

To add sections between sections 3.1 and 3.11:

• 3.1
• --- 3.101
• --- 3.102
• --- 3.103
• --- 3.104
• 3.11

To add sections before section 3.1 and between sections 3.103 and 3.104 and after section 3.11:

•   3.
• --- 3.01
• --- 3.02
• --- 3.03
• 3.1
• 3.101
• 3.102
• 3.103
• --- 3.1031
• --- 3.10311
• --- 3.1032
• 3.104
• 3.11
• --- 3.111
• --- 3.112
• 3.2

To add paragraphs after paragraph (z) (the letter, period and number are italicized):

• (z)
• (z.1)
• (z.2)

Notes :

In the rare case that an existing regulation has paragraphs following paragraph (z) and designated as (aa), (bb), etc., the same system is to be used in the amendments, unless paragraphs are being inserted between paragraph (z) and paragraph (aa). In that case, the alphanumeric system should be used, for example z.1.

Items in schedules are also identified using Arabic numerals, which may or may not be in boldface (see SCHEDULES TO REGULATIONS).

Specific rules apply to the numbering of parts, divisions and subdivisions in regulations (see DIVISION OF REGULATIONS).
