Members of Parliament were elected in 16 multi-member constituencies (of between four and sixteen seats) coterminous with the Districts of Sierra Leone by proportional representation via the largest remainder method (with the Hare quota),[7][8] after a presidential decree by Julius Maada Bio in October 2022 abolished the first-past-the-post system that had been used since 2008.

The Supreme Court of Sierra Leone ruled that the decree changing the electoral system was constitutional in a case brought by opposition MP Abdul Kargbo and local councillor Hakiratu Maxwell-Caulker.

[10] Incumbent president Julius Maada Bio was re-elected with 56% of the vote, a result which was contested by the main opposition party, the All People's Congress, which demanded a rerun, citing "glaring irregularities".

[5][6] Sierra Leone's chief electoral commissioner, Mohamed Kenewui Konneh, said that it would take time to upload the disaggregated results to the internet.

[5] The election itself was conducted largely peacefully according to observers from the Commonwealth of Nations,[11] although one female nurse was killed at the headquarters of the All People's Congress after government forces fired shots and tear gas as voters awaited the announcement of the results.
