Initially, the vote was challenged by the losing candidates. However, in November 2011 the Constitutional Court rejected the challenges clearing the way for Ratu Atut to become governor of Banten for a second time. She was sworn into office for a five-year term 2012–2017 by minister of the interior Gamawan Fauzi on 11 January 2012.  2013  On 3 October 2013 Ratu Atut was forbidden from travelling overseas by the Indonesian Immigration authorities on account of a number of corruption investigations in which her family was suspected of involvement. The imposition of the travel ban, and the reports that her brother Tubagus Chaeri Wardana (often known as "Wawan") was involved in a case of bribery involving the Chief Justice of the Constitutional Court, encouraged some Banten residents to stage a protest outside the Indonesian Corruption Eradication Commission ("Komisi Pemberantasan Korupsi" or KPK) about her activities as governor of the province. On Friday 11 October 2013 Ratu Atut, in response to an official summons, attended a session at the KPK to answer questions about the bribery case involving her brother. Issues of possible corruption surrounding Atut's family widened significantly in late October when the KPK announced that an investigation had been launched into matters under the administration of Atut's sister-in-law, Tangerang Mayor Airin Rachmi Diani. The investigation, into alleged irregularities in the procurement of medical equipment in South Tangerang, were said to be into matters entirely unrelated to the bribery investigation concerning Airin's husband, Tubagus Chaeri "Wawan" Wardana. The row over issues of possible corruption in Atut's family continued to attract close media attention during November 2013. On 17 December the KPK took the significant step of formally naming Atut as a suspect in connection with her alleged role in the suspected bribery of the chief justice of the Constitutional Court. On 20 December, in the midst of considerable publicity, she attended a formal session at the KPK to answer questions relating to her alleged involvement in corruption. According to press reports, around 1,000 police were mobilised to ensure order in the streets near the KPK and around 40 busloads of her supporters gathered to protest the investigation into her activities. Later in the day, the KPK formally arrested Atut and placed her under detention. Media reports quickly highlighted the sharp change in her personal fortunes, noting the contrast between her lifestyle as governor of Banten when she had lived in relatively lavish surroundings and conditions in the detention centre where she had been placed in Jakarta.  2014  In early January 2014, the KPK widened investigations into Atut's family dealings in Banten.
