8 provisions changed · 9 provisions added · 2 provisions in the supplementary provisions · 2 provisions moved to another number

Each provision the amendment changes, as it will read: the words it adds are underlined, and a bar marks where it removes words. “Show removed words” strikes those through in place; “Before and after” sets the two wordings side by side. A provision that only moves to another number says the number it had. The Japanese is the law; the icon beside each English column says whose English it is.

How the changes are shown

Underlined: words the amendment adds. A bar: where it removes words.Underlined: words the amendment adds. Struck through: the words it removes.Underlined: words the amendment adds. Struck through: the words it removes.
