Not sure I understand the reasoning here. Making the judiciary elected directly instead of appointed would make them less independent? Seems like they’d be more independent from the rest of the state. There certainly are pros and cons to different judicial systems but this particular complaint doesn’t make sense.
I wonder if the real concern is that instead buying off just the president they’d also have to buy off the judiciary if they wanred to have more influence in Mexican politics. To be fair they seem to have trouble buying off the president anyway.
