Codification is the process of bringing together a legal act (or several related acts) and all its amendments into a single new act.

Codification can take 2 forms:

  • vertical: where an original act and its amendments are incorporated in a single new act; or
  • horizontal: where 2 or more original acts covering related subjects, and any amendments to them, are merged in a single new act.

Unlike in the case of consolidation (i.e. the unofficial simplification of a legal act incorporating its amendments), the new act goes through the full legislative process (e.g. ordinary legislative procedure, consultation procedure or consent procedure) and replaces the acts that are being codified.
