Ignoring protests from the opposition bloc and pensioners, the ruling triumvirate on Tuesday rammed through an Upper House committee a package of bills that is supposed to save the nation's nearly bankrupt pension system.

The vote, which was not originally scheduled for Tuesday, was held after the committee held a public hearing and a question-and-answer session.

The controversial bills, which are intended to gradually curtail the benefits of income-proportional public pensions for salaried workers by 20 percent by 2025, is expected to clear the Upper House plenary session today.
