take office. The Standing Committee presents a report to the CCDI at every plenary session; the latter is the only national-level organisation, with the National People's Congress and the Central Committee, which holds at least one plenary session a year. CCDI plenary sessions, which discuss its past and future work, are usually held in January. The 18th Standing Committee has 19 members, one of whom (Huang Xiaowei) is a woman. The CCDI employs about 1,000 people. Since the 1993 merger of its internal functions with the MOS, it has grown to 27 bureaus and offices; of these, the Office for Discipline Inspection and Supervision, the Case Hearing Office and the Office for Circuit Inspection Work are the most important. ODIS and its ten divisions are responsible for investigating breaches of party discipline and unlawful acts by party members. Of the ten divisions, four investigate cases at the vice-ministerial level and above; the remaining six investigate "officials at the level of provincial governor, vice-governor, chair and vice-chair of provincial standing committees of the National People's Congress, chair and vice-chair of provincial Political Consultative Conferences, city mayors and deputies." In addition, there are twelve institutions which are directly subordinate to the CCDI. Lower levels and inspection teams Below the central level there are several commissions for discipline inspection (CDI). The CDI's composition is decided by the CDI a level above it, and endorsed by its party committee and the committee superior to it; the establishment of discipline commissions at the local level is decided by the upper-level party committee. The main duties and responsibilities of local CDIs are to educate party members on their duties and rights, preserve party discipline, uphold party decisions, see that party members exercise their duties in accordance with the party constitution, examine cases and investigate corruption. It is expected to report its findings regularly to its corresponding-level party committee. If a member of the local party committee is involved in corruption, the local CDI should ask the party committee at the corresponding level and the CDI at the level above to approve a full investigation. Before the 2014 reforms it was difficult for the CDIs to carry out their responsibilities; although they no longer needed approval from the secretary of the corresponding-level party committee, CDI officials were often appointed to positions of power within the institutions they were tasked to supervise (see above). The 2004 reforms increased
