🇿🇲 EXPLAINER | When will Hichilema be sworn-in? What happens if Mundubile petitions?

President-elect Hakainde Hichilema could be sworn-in for his second term on Tuesday, September 1, 2026, but one important constitutional question remains unresolved: will Brian Mundubile challenge the presidential result before the deadline?

Hichilema was declared winner of the August 13 presidential election by the Electoral Commission of Zambia in the early hours of August 18. He received 2,965,326 votes, while Mundubile received 1,856,217, leaving a margin of 1,109,109 votes.

Under Article 103(1) of the Constitution, a person seeking to challenge the election of a President-elect has seven days from the declaration to petition the Constitutional Court. Article 269 governs the computation of time and excludes the day on which the triggering event occurred. On this calculation, August 19 becomes Day One and Tuesday, August 25 becomes Day Seven.

This means Mundubile still has until the end of Tuesday to move from political rejection of the result to a formal constitutional challenge. He has already said NRPUP documented irregularities involving the handling of electoral materials, ballot security and differences between polling-station figures and the final tally. “We have enough evidence and records to submit to appropriate institutions within the stipulated period,” he said earlier.

But announcing an intention to petition is not the same as filing one. Until a petition reaches the Constitutional Court, the constitutional timetable continues towards inauguration. Mundubile’s allegations would also have to be tested through evidence before the court; rejection of an ECZ declaration by itself does not alter the declared result.

If a petition is filed, Article 103(2) requires the Constitutional Court to hear and determine the matter within the constitutionally prescribed period. That would interrupt the straightforward path towards a September 1 inauguration while the challenge is considered.

If nobody petitions by August 25, the position becomes much simpler. Article 105(2)(a) provides for the President-elect to assume office on the Tuesday following the seventh day after the declaration where the election is not challenged. On the dates arising from this election, that points to Tuesday, September 1.

There is also a political dimension. Mundubile continues to dispute the presidential result, but important figures around the opposition arrangement have begun moving in another direction. NRPUP president Ezra Tembo has accepted Hichilema’s victory, while Tonse founder and secretary-general Chris Zumani Zimba has publicly said he will not support a presidential petition.

So Zambia is now approaching a clear constitutional fork. By Tuesday night, the country should know which road it is taking: litigation before the Constitutional Court, or preparations for Hichilema’s September 1 inauguration.

For now, Hichilema remains President-elect. ECZ has declared the election. The petition window remains open. The next move belongs to those challenging the result.
