How we keep these pages

  • Primary sources only. Every entry is checked against the text of the agreement or statute in the official legislation databases, and the links point to those texts, not to summaries.
  • You can see what changed, and when. Each page carries its update date and a “Recent changes” block: a new ratification or signing order appears there with the date of the act.
  • We watch for changes weekly. New ratification laws and signing orders are checked on a schedule, not when someone happens to notice.
  • Know more? Tell us. If you are aware of an agreement or a change not yet reflected here, let us know and we will verify it and update the page.
