Abraham Amaliba, a member of the National Democratic Congress (NDC) legal team says the party might challenge the result of the 2016 presidential poll in court.
In an interview with Accra-based Joy FM, Amaliba claimed there were some irregularities recorded in some regions of the country, especially the Ashanti Region.
He said data from the NDC's tabulation of the result had Mahama winning the election by a slight lead.
However, he said if things don't go well, the NDC may decide to pursue a case in court.
"We have lawyers collating those pink sheets and will handle it at the appropriate time," he said, adding: "A decision may be taken either to go to court."
Meanwhile, Joy FM's collation of data from 267 constituencies has Nana Akufo-Addo leading by 53.35%. Mahama is second with 44.85%.
