A prominent human rights group says Bolivia has undermined judicial independence by arbitrarily dismissing nearly 100 judges since 2017 and it's asking the Organization of American States to address the issue.

Human Rights Watch says the judges haven't been given any reason for the dismissals by a Magistrates Council dominated by allies of President Evo Morales.

It says even judges who supposedly had permanent positions have been ousted.

Monday's report says the firings appear to violate international treaties requiring an impartial judiciary.

The organization's America's director Jose Miguel Vivanco says the firings should be "a wake-up call for OAS member states."

He says that when Bolivians "can no longer expect judicial independence, then their rights are at risk."

Government officials say they won't comment until reading the report.
