Reading the verdict of the apex court, it is clear the majority based their decision on technical breach of procedure rather than on the substantive merit of the case against INEC.

A legal technicality is a small but ultimately important detail of the law. When a case is decided based on “a technicality”, it means the defendant would have been in trouble for something but through some small oversight or misinterpretation of a rule, they are found not guilty.

The apex court in a split decision of five to two members of the panel, on Friday, agreed substantially with the Court of Appeal which ruled that a majority judgement delivered at the tribunal was a nullity. The court said the judge who had read the majority judgement at the tribunal, Justice Peter Obiora, was “evidently absent” on February 6th, 2019, following the documents before the court. In this case, the Supreme court says because the Lead judge in the Tribunal did not sign the attendance sheet on 6th February, it is assumed that he was not in attendance; hence cannot be a judge in a case he did not hear its facts and details.

Supreme Court Ruling On Osun Gov Poll: Victory By Technical Justice Calls For Sober Reflection On Nigerian Justice System By Dr. A.S Ishola

Like many other cases similarly decided by the Supreme Court, the incumbent Governor of Osun State has won his election petition at the Supreme Court on technical ground. I do strongly believe that technical justice is a legal way by which injustice is still allowed to thrive in our justice system. If beneficiaries of technical justice were to be guided by Islamic justice tenets, they would realize that, if by technical justice, they are judicially given what does not belong to them, it is hell fire that is being handed over to them. This is how Prophet Muhammad used to admonish the litigants that came to him. The same also goes to lawyers who employ technicalities to defeat the course of justice which they themselves glaringly know. Like Professor ALARO said, such technical justice lawyers who are Muslims should warn themselves lest their legal practice become the price they pay for their divine salvation in the hereafter. For judges, Islamic law has made it clear that there are three types of judges and only one of them will earn the divine pleasure of their Creator. For any litigant that is denied his entitlement on technical ground, let him be comforted that his prayer as an oppressed person has direct entrance to his Creator. The above is not however in particular reference to the recently delivered judgment of the Supreme Court, but on the need for our justice system to do away with technical justice practice. Many tears are out there which have refused to dry up because they were denied what belongs to them by technical justice.
