When did current edition start automatically superseding previous?

[Atul Kapur]

The language on p. vii that begins, "This Twelfth Edition supersedes all previous editions and is intended automatically to become the parliamentary authority . . . " also appears (with the correct edition number) on p. vii of the 11th edition and p. II of the 10th.

In which edition did this language first appear?

Prior to that, was there another rule or was this (or similar) language felt to be simply an explicit statement of what was previously considered understood?

General Robert never said any such thing as "supersedes" and I cannot find any such language to the effect that any edition "supersedes" anything before the 1970 edition. There was no "another rule" or anything similar. I have the text for all editions 1 through 6 in order to prove this.

The latter, I would assume.

Thank you.
