Prosecuting organs have investigated 24 people allegedly involved in reduced prison sentence and early release of Zhang Hai, former board chairman of Jianlibao Group Co. Ltd., the Supreme People's Procuratorate (SPP) said on Monday.

最高人民检察院周一表示，检察机关对健力宝集团原董事长张海违法减刑系列案共立案24人。

“减刑”（commuted/reduced sentence，commutation of sentence）是对于被判处管制(put under surveillance)、拘役(detention)、有期徒刑(fixed term imprisonment)、无期徒刑(life imprisonment)的犯罪分子，在执行期间确有悔改或者立功表现的，适当减轻其原判刑罚(reduction of legal penalty)的制度。

“假释”（parole，conditional release）是对被判处有期徒刑、无期徒刑的犯罪分子，在执行一定刑期之后，因其遵守监规，接受教育和改造，确有悔改表现，不致再危害社会，而附条件地将其予以提前释放的制度。

“暂予监外执行”（temporary service outside prison）指对有严重疾病需要保外就医的、怀孕或者正在哺乳自己婴儿的妇女以及生活不能自理、适用暂予监外执行不致危害社会的被判处有期徒刑的罪犯，批准其在一定期限内在监外服刑的制度。
