The Supreme Court judges will from Tuesday hear the appeal case on the Building Bridges Initiative (BBI).
The Court of Appeal in August upheld the High Court ruling that BBI is null and void and its processes were unconstitutional.
In a three-day sitting, the apex court will hear the appeals filed by Attorney General Kihara Kariuki, city lawyer Morara Omoke and the Independent Electoral and Boundaries Commission .
The Attorney General On Tuesday put up a spirited fight before the apex court in a bid to revive the annulled Building Bridges Imitative (BBI) process.
Through Solicitor General Kennedy Ogeto, the AG faulted the Court of Appeal for declaring the BBI process unconstitutional.
Ogeto told the seven judges, led by Chief Justice Martha Koome, that their singular desire is that the court determines and settles the constitutional questions in their appeal.
"Not just for today but also and perhaps more importantly for posterity," he said.
He said Court of Appeal judges answered important questions the wrong way, ambiguously and gave contradictory justifications in some cases.
On Monday, parties in the BBI appeal said they are disgruntled with the time allocated to them by the Supreme Court.
Last Friday, the Deputy Registrar of the Apex issued directions to parties on how the case will be conducted for the three days that it will be heard.
A source who requested not to be named because he is close to the case said the Supreme Court is in an unnecessary rush even though the matter is no longer going to impact the next general elections.
The court had directed that the Attorney General and IEBC who are appellants will have 45 minutes each to highlight their submissions.
