The Supreme Court judgment followed a pattern seen in previous presidential elections that have been challenged in court.
Speaking for the first time since the ruling, Obi, a former two-term governor who campaigned as an outsider, told reporters the judgment was a disappointment and contradicted overwhelming evidence of election rigging, false claims of technical glitches, and other irregularities.
Obi's supporters, known as the "Obidients", have been vocal in their criticism of the Supreme Court ruling.
They have accused the court of being biased and of protecting the interests of the ruling party.
Obi's rejection of the Supreme Court ruling is likely to resonate with his supporters, mostly young Nigerians who were attracted by his message of hope and change and see him as a break from the old guard.
