The audience for this research are investors. Besides being a public policy forum, (lobbying group, PR), this "institute" also has an investment firm branch. Its very obvious that whoever has conducted and commissioned this highly questionable report, had only one thing in mind that is to show a "clean" Tanzania, with people confident in their judiciary to lure investors.
(A US study conducted in 2009, by State Dept. the Tanzanian judiciary was found to be the most corrupt. Recently, EA bribery index came up with the same results.)
Since 2009, when the article on GRAND corruption was suppressed, there has been no GRAND corruption articles mentioning the corrupt officials in the local media. Last year, when people wanted to protest the DOWANS ruling, police banned protests. WHY?
Because seems like the Tanzania government wants to suppress the reality of investing in Tanzania, and the reality that there are corrupt officials in the government, and that corruption is the status QUO, the system prevalent today in TZ. The reality is that today in TZ the health sector, the education sector, rule of law, the infrastructure all is suffering due to a corrupt system in place.
