编辑同志：我们在审判实践中遇到如何认定行政处罚时效的问题。原告曹某1993年未经有关部门批准，私自盖了一间平房。被告某市建设委员会当时发现了，但未予处罚。1999年，被告经调查核实，对原告的建房行为作出处罚决定。对该案处罚时效如何认定的问题，有两种意见。一种意见 Editor’s Comrade: We encountered in trial practice how to determine the limitation of administrative penalties. The plaintiff Cao in 1993 without the approval of the relevant departments, privately built a bungalow. A city construction commission was found, but not punished. In 1999, the defendant, after investigation and verification, imposed a sanction on the plaintiff’s building operation. There are two opinions on how to determine the limitation of punishment in this case. A comment
