This is an area where we need to be very careful. Presidents, prime ministers, and sometimes all membersof a government, seek to amend a constitution in their own favour even when they come to office through, and because of, the provisions of a constitution which they have sworn to honour. Too often, for example, we have seen presidents seek to lengthen the number of terms they serve, despite the limit laid down in the constitution. This practice is wrong. It cheapens the constitution of the country concerned.
Cheapening constitutions make the new nations weak politically. Allow for more neo-colonialism through instability.
