In 1971 he was appointed to become the Minister of Justice and Constitutional Affairs of Uganda, by new President Idi Amin, a high-profile cabinet role he was appointed to despite his apolitical nature- Nkambo Mugerwa was a civil servant who was not a member of any political party which let him be one of the few ministers from Apolo Milton Obote's cabinet to continue as a cabinet minister or be promoted when Idi Amin staged his coup.

In 1973, Idi Amin fired his Minister of Justice and Constitutional Affairs of Uganda, Peter James Nkambo Mugerwa, with the stated reason being that he could not keep up with the "supersonic speed" that President Idi Amin was driving the economy, leading him to appoint Godfrey Serunkuma Lule to be his successor.

After he was sacked by Idi Amin, Nkambo Mugerwa entered private practice and partnered with former Buganda Attorney General Fredrick Mpanga to form Mpanga and Mugerwa Advocates. After the death of Fredrick Mpanga he partnered with M.B Matovu to form Mugerwa & Matovu Advocates.

Mugerwa & Matovu Advocates later changed to Mugerwa and Masembe Advocates when he partnered with Timothy Masembe Kanyerezi, Mathias Ssekatawa and Phillip Karugaba. 

This partnership laid the foundation to form MMAKS Advocates a top tier law firm in Uganda. 

He retired from legal practice and mainly spent time between his farm and lakeside property in Mukono District and ranch in Kyankwazi District. 

He also reentered public life when Kabaka Ronald Mutebi appointed Nkambo Mugerwa to be the chairman of the Buganda Land Board, taking over for James Mulwana who had to resign after an "operation weakened" him. He oversaw a 13-person board, including Prince David Kintu Wassajja, Kabaka Mutebi's younger brother, the Luweero district chairman, Hajji Nadduli Kibaale and Martin Kasekende, the managing director of National Housing and Construction Company.
