He was tried again upon his return to the country, and sentenced again. From what I remember he appealed and the case is still in limbo. The Fern?ndez government/ the judiciary during his goverment have not touched the case so far.
It is widely accepted that there was corruption in the Jorge Blanco government, but there was more corruption in the government that followed, that of former President Balaguer under whose government Jorge Blanco was prosecuted. Thus the main reason why people say the case was politicized.
The government of Jorge Blanco was a major disappointment. He was a young President and expectations were high. Jorge Blanco was elected into government with the promise of a clean government (he even paid the highway tolls), and this was true during his first two years of government. Things changed in his last two years of government, and since expectations of a change were high (from the corruption of the Balaguer years), there was much more disappointment.
