Kenya's 2010 Constitution marked its 15th birthday this week, complete with a presidential proclamation that recognised the 27th of August as Katiba Day.

It is easy to pour scorn on the declaration, especially as it does not deliver a holiday, but focusing on the Constitution for one special day is critical for reminding us what the Katiba means.

In 2010, when the Constitution was promulgated, there was hope in the air.

By 2013 when we held the first elections under the new law and established the devolved system, Kenyans had great expectations that their lives would finally have meaning.
