Okay Creamy I'll bite here's a link for Annex 13 9th edition with amendment 11 incorporated, which lists the effective date for the amendment as 13 July 2006:

So the next amendment we're interested in is amendment 12, so here is a link for Annex 13 10th edition, which lists the effective date for amendment 12A and 12B as 20 July 2009. However both 12A&B deal with (a) definitions of runway incursion incidents and (b) State safety programs and voluntary incident reporting systems...blahblah.
Which leaves amendment 13 which was effective on 12 July 2010 and was subsequently in edition 10. And this amendment would appear to have dealt solely with Chapter 5 'Investigations'.

Anyway I'll let you do the reading and if you still aren't happy well I'll let you track down a Annex 13 9th edition with the amendment 12 incorporated...
