A minister and some inspectors who refused to be sworn into office, taking the oath on a Christian or Muslim religious text, have been sacked. It is now mandatory for high-ranking officials to undergo this process before assuming office. The regulations apply not only to civil servants but also to deans of universities and other top public servants.
Christian organisations are protesting because this new process has not, according to them, done anything to curtail corruption.
They say that the recent sacking of a government minister proves that it hasn't made any difference.
A petition, drawn up by Christian organisations, is circulating which aims to have the religious oath of office removed from the constitution.
The petitioners feel that the condition will force Christians out of public office.
Some religious leaders, fearing reprisals, have not communicated the petition to their parishioners.
The Christian organisations who have initiated the petition say that it is open to all Chadians of any faith. They hope to secure sufficient signatures to submit the petition to the government.
