The government acknowledged Friday that pension reform legislation enacted by the Diet last month contained as many as 40 technical flaws, and reprimanded bureaucrats in connection with the fiasco.

The latest development regarding the unpopular legislation is likely to provide opposition parties with more ammunition in their campaign to have the reforms scrapped.

The government insisted that the mistakes are minor technical matters and will not require any revisions that would have to clear the Diet. Posting a notice of the errors in the official government gazette will suffice, officials said.
