The expulsion of Dr Emmanuel Nchimbi from the ruling Chama Cha Mapinduzi (CCM) has raised constitutional questions over whether losing party membership automatically ends his tenure as Vice President.
However, Advocate Paul Kisabo, Head of the Legal Defence Unit at the Tanzania Human Rights Defenders Coalition (THRDC), says the Constitution does not provide for the automatic removal of a sitting Vice President solely on the basis of losing membership of the political party that sponsored his nomination.
The debate follows Dr Nchimbi’s resignation as Vice President, which he submitted on August 25, 2026, indicating that it would take effect on September 4, 2026.
Dr Nchimbi was subsequently expelled from CCM, prompting questions from members of the public and legal commentators over his constitutional status between the date of his expulsion and the effective date of his resignation.
According to Advocate Kisabo, the answer lies in distinguishing between the constitutional requirements for becoming Vice President and the provisions governing how a Vice President leaves office.
He cites Article 47(4)(c) of the Constitution of the United Republic of Tanzania, which requires a Vice Presidential candidate to be a member of, and sponsored by, a political party.
Article 47(4)(d), he adds, requires the candidate to possess qualifications that would enable them to be elected or appointed as a Member of Parliament or a Member of the House of Representatives.
“These are constitutional qualifications for a person to become a candidate for the position of Vice President,” Kisabo explains.
But once a person assumes the office, he argues, the relevant constitutional provisions are those dealing with the termination of the Vice President’s tenure.
Kisabo refers to Article 50(2), which sets out circumstances under which the office of Vice President may become vacant.
Among them, Article 50(2)(c) provides for the Vice President continuing in office until resignation, while Article 50(2)(h) covers other circumstances provided for under the Constitution.
The lawyer says there is no express provision under Article 50(2) stating that a Vice President automatically ceases to hold office after losing membership of the political party that sponsored his nomination.
“That is different from the constitutional position of a Member of Parliament,” Kisabo says.
He cites Article 71(1)(e), which expressly provides that an MP ceases to be a Member of Parliament if he or she ceases to be a member of the political party to which they belonged when elected or appointed. For Kisabo, the difference is legally significant.
Where the Constitution intends loss of party membership to result in the loss of a constitutional office, he argues, it says so expressly.
“The Constitution has expressly provided for loss of office in the case of a Member of Parliament upon loss of party membership. There is no similar provision under Article 50 concerning the Vice President,” he says.
The lawyer also points to Article 149(2) of the Constitution in explaining the significance of the date contained in Dr Nchimbi’s resignation letter.
The provision establishes that where a person submits a written resignation and specifies the date on which it is to take effect, the resignation takes effect from the date stated.
In Dr Nchimbi’s case, Kisabo says, the specified date was September 4, 2026.
“Therefore, based on these constitutional provisions, the expulsion from CCM does not, by itself, automatically terminate Dr Nchimbi’s position as Vice President,” he says.
“Since his resignation letter specified September 4, 2026 as the effective date, the resignation takes effect constitutionally on that date.”
The interpretation comes amid heightened public interest in the constitutional procedures surrounding the Vice President’s office and the circumstances under which the holder can cease to serve.
It also highlights an important constitutional distinction between eligibility for appointment to office and grounds for leaving office—a distinction that Kisabo says is critical in understanding Dr Nchimbi’s current position.
