As a Colombian senator, I supported the appointment of the inspector general, Alejandro Ordóñez, because of my belief in the importance of political pluralism, even though he is a close ally of the right-wing former president Álvaro Uribe (who has criticized his successor, Mr. Santos, for talking with the FARC).

While the inspector general has power, under the Constitution, to remove certain officials, in my case Mr. Ordóñez has overstepped and abused this authority. In attempting to disqualify me from participation in politics on the flimsiest of pretexts, Mr. Ordóñez is trying to end my political career and weaken the political left. He is also trying to deal a blow to the peace process with the FARC.

It is precisely because of this overreach that many in Colombia are calling for a reform of the inspector general’s powers, so as to require judicial review before an elected official can be removed. This would bring our Constitution into line with the American Convention on Human Rights, a treaty that Colombia has ratified. It provides that elected officials may be removed only after being convicted by a competent judge in criminal proceedings.

The grounds for my removal are preposterous. Last December, I tried to break the oligopoly of private companies that held the contracts for garbage removal. My administration estimated that these companies had overcharged the city some $300 million in the decade before I took office. Those companies, previously concession holders, are now contractors with the city.

I acknowledge that my government made mistakes that are not uncommon when changing the model for provision of a public service as complex as trash collection in a city with millions of residents. But Mr. Ordóñez has accused me of no crime. He says, among other things, that my administration mishandled our effort to bring trash collection under public control, and in so doing attacked the system of “free enterprise.” He also says that the accumulation of several thousand tons of garbage on Dec. 18-20, 2012, threatened public health. He does not demonstrate how this justified the removal of the democratically elected mayor of the nation’s capital.

Mr. Ordóñez’s background shows a pattern of intolerance. As a student in the northern city of Bucaramanga more than 30 years ago, he participated in the mass burning of books considered “impious” from a public library. These included Protestant translations of the Bible (Mr. Ordóñez is an ultraconservative Catholic) and works by Gabriel García Márquez. As inspector general, Mr. Ordóñez interfered with the construction of a women’s clinic in Medellín, on the theory that abortions might be performed there. He also threatened to remove judges and notaries who performed same-sex marriages, even though the country’s Constitutional Court ruled in 2011 that same-sex couples could join in “solemn union.”
