Obviously when agamew Meles and Galaw Lencho sat together to draft it, they were not looking beyond their nose and only thought of Tigray and Oromia.
7 of the remaining states are too large to be ignored so they gave them statehood. The remaining 78 ethnicities were too little or irrelevant to be placed on the map. The flaws of this trashy constitution begins there and it has no end point.
Fast forward 30 years, the Gallas granted Sidam statehood because it is considered an ally and it will tarnish the southern states by taking the capital (hawasa) they built and handing it over to Sidama.
Gurage now demanded statehood following the same book Galas and Agames use. Gurage will achieve statehood because it convinced it's population and fulfilled all criteria. Galla Biltsigina is now in complete shock not knowing about what to do on Welaytas quest for statehood and the remaining 77 ethnicities.
Ethiopia is led by a trash constitution that is a joke by western standard.
