In a petition filed on Friday NASA laid down reasons why it claims the August 8 election was fatally compromised.
First, the opposition first alleged that there were numerous instances in which votes were deducted from their flag bearer and added to President Kenyatta.
Secondly, an affidavit by Mombasa Governor Hassan Joho Economic Adviser claims that he had examined over 25,000 vote declaration forms and detected errors in 14,000 forms.
He stated that the errors included unsigned documents and the name of one presiding officer being shown as the official in charge of elections in multiple stations at the same time.
According to the petition, there were 443 instances of ungazetted polling stations, election results forms that had been filled out in the same handwriting.
It adds that there were forms that had a polling station, names and details of agents as well as their signatures but did not have any results.
Other documents in the NASA petition also alleged that the votes cast in the presidential election (15,588,038) exceeded those for governors (15,098,646) and Members of the National Assembly (15,008,818) by 482,202 and 567,517 ballots respectively.
NASA further accused the Independent Electoral and Boundaries Commission (IEBC) of flouting a number of laws including electronic transmission of results by image and text to the tallying centre, and the display of results in a public portal that is accountable, verifiable and accurate.
The opposition further notes that IEBC Chairman Wafula Chebukati had not received all the tallies from all polling stations by the time he announced the final results.
Lawyers working on the NASA court papers questioned why IEBC declared results for the presidential election without having documents from all the polling stations.
Finally, the petition claims that returning and presiding officers were recalled to fill and adjust relevant results forms to ensure documents tallied with the final results announced.
