From a business background, business law comprehension, and in addition to certain degree of personal visits to constitutional script - my attitude is firm towards 'NOTHING BEING WRONG WITH OUR CURRENT CONSTITUTION'.
Presidents and heads of states alike - globaly - utilize the executive branch of the government to drive forth what they believe is consensually profound to varying degree.
I understand one of the major talking points moreso in the wake of proceedings across the boarder (Kenyan 2022 elections) - is in regards to agenda with the Tanzanian Electorial Council - and an independent council being put forth prior a new constitution.
If evident - then this is a major move in mobilizing for the 2025 elections - be it from the party in power or the opposition.
As a disclaimer - I strongly and progressively entail tendencies towards pan African directives and I like to consider myself a free thinker, where in the past have been heavily swayed towards the leading opposition party. If anything, this composition ought not be mistaken for siding with any party in regards to my stance. And with such, I firmly back my belief that 'THE CONSTITUTION IS FINE AS IT IS' and that any call for reform is redundant!
The problem rather, can be found in the bureaucratic system (s) as with all globally, and reason being bureaucracy as a term is utilized with disdained property.
Stronger institutions across the board nationwide should be the calling card in the form of sound personnel and efficiency.
Change comes from the inside, and in practical instance, the national election council for example (or any other institution at that nationwide, private or public) ; where individuals not happy with current landscape ought look to set in motion events that will neutralize way of conduct from the inside by assuring individuals with capacity to drive agenda and carry out tasks of moral consensus are of avail.
In addition to topic of an independent electoral council / commission - such isn't always of constitutional mandate in all locales / nations that have an independent EC. Furthermore - "Election commissions can be independent, mixed, judicial or executive." Telling models are all dependant on what shaped regional democracy.
Adding subtle substance to 'stronger institutions' and 'internal neutrality' - we ought assure that other branches of the government, aside that of the executive or moreso, that directly stemming from the presidents office - play their part within these institutions as opposed to tearing down profound systems that are moreso inclusive of broader consensus on many levels.
N.B. The current constitution entails elements of sheria law for those who practice it (Zanzibar) - in addition to local tribunals for local and domestic disparities - prior escalation to further structured proceedings, aiding those at ground level with possible limitation to educational and financial reserve to take up a full blown law suite. That, in addition to other nuances is what has shaped a unique rule of law upon the republic with peaceful inhabitants.
