刑事案件没有时效。唯一的例外情形是青少年犯罪（重罪为 10 年，轻罪为 5 年）和海关犯罪（3 至 10 年，依案件类型而定）。
There is no statute of limitations for criminal cases. The only exceptions are with respect to juvenile offences (10 years for felonies, 5 years for misdemeanors) and customs offences (from 3 to 10 years, depending on the type of case).
