That's a start, thank you. Now, here is what you wrote:
Chebukati is the presidential returning officer.
Which part of that document supports that claim? From what I gather, the term "returning officer" is explicitly defined in the law, as are the associated tasks and powers, and the definition and other text suggest that no member of the IEBC can function as a "returning officer" of any sort. (I could be wrong, although I went through the relevant documents and took a look at all they had to say about "returning officers".)
You also write that:
For MP & MCA - the const Returning Officer is final. For govenor, senator and women rep - the County RO is final. For presidential - the Chair of IEBC as the RO is final.
Which part of the law supports that claim? As far as I can see, there is no such distinction. In fact, a quick look shows the constituency returning officer has an equal role for all positions--MCA, MP, Presidential.
And page 14 seems quite clear on Chebukati's role:
I see no problem with any of that.
Basically, he is to---
(i) check that the numbers he has been given match those on the forms signed by the constituency returning officers;
(ii) do the sums on the sgned-for numbers;
(iii) sign some form;
(iv) announce the results.
That's it.
All that seems to be far less that the powers you have been claiming on his behalf; and it could, as Terminator suggests, all be done by machine. In particular, I don't see the basis on which he would be able to change anything from the constituency level or where he has room to argue with the numbers signed for at the constituency level. So, as in most places, people ought to be able to "call" the results simply by looking numbers declared at the lower level, and unless Chebukati has some magical calculator that would yield different sums, he has no more say over "presidential" numbers than he has over "lower level" numbers ... basic checks and signatures.
What have I missed or not understood?
