Timing of regional family laws in Ethiopia

Question:
When did Tigray, SNNP, and Oromiya implemented their regional family codes and which components of these laws differ from the Federal Revised Family Code of 2000 (Proclamation No. 213/2000)? Your library includes a link to the English version of Amhara’s Family Code of 2003 (Proclamation No. 79/2003), but I cannot find English versions for the other regions. According to Hallward-Driemeier and Gajigo, Amhara, Oromiya, and Tigray updated their family codes between 2000 and 2005 and SNNP did so between 2005 and 2011. I would like to know the precise years in which these regions, and especially SNNP, implemented their family codes.

Response:
I do not know of copies of the Revised Family Law in English for any state except Amhara.
Tigray passed its own Family Code in 1998, which served as a model for the Federal Code. The Tigray Region Family Code was revised in 2007.
The Oromia Regional State Family Code, Proc. No. 83/2004 passed in 2004.
The SNNP Family Code was passed in 2004, so implementation would have started in 2005. The Southern Nation, Nationalities and Peoples Regional State’s Family Code Proc. No. 75/2004, Debub Negarit Gazetta, 9th Year, Extraordinary Issue No. 1 passed in 2004. I was unable to find it in English, but here’s a comparison of the Federal Family Code and the SNNPR Family Code.
