Some independent commissions could be set up, but ultimately, they would remain in the hand of the power. Though, in such a system, if the power touch to an independent commission the people would more easily and more strongly protest. Like if they touched to CNIL in France (concerns protection of personal data).
Sarko shoved a so-called 'independent' commish to give, more or less, a blank cheque to the Chief Gerrymanderer, that piece of crap Marleix. Headed by Yves Guena, a rightist, it only did something if the constituencies were
really,
really awful.
But people don't care about electoral constituencies as much as they care about something like CNIL since you have tons of people who don't vote, people who are party hacks and votes whichever ways their party tells them to and so forth.
