BEIJING - China's newly introduced legal interpretation on handling dereliction of duty cases has highlighted that officials involved in covering up accidents should be handed aggravated penalties.

According to a statement issued on Tuesday by the Supreme People's Court, the legal interpretation has for the first time specified criteria in convicting criminal offenses of power abuse and dereliction of duty. It explains what kind of scenarios will be considered as "resulting in grave damages to public assets, interests of the state and the people".

These scenarios include accidents involving a fatality or fatalities, three or more serious injuries, or nine or more minor injuries; incidents involving more than 300,000 yuan ($48,210) of economic losses; incidents exerting baleful social influences.

The legal interpretation stressed that if officials are involved in cover-ups or delayed reports of accidents, or coerce others to cover up, and the damages fail to be curbed as a result of cover-ups, they will be handed aggravated penalties.

In a recent case, a subsidiary of the China Railway Tunnel Group purposefully concealed a fatal railway tunnel explosion that occurred on Dec 25 in North China's Shanxi province.

Eight people were killed and five were injured in the explosion in a railway tunnel that was under construction.
