National Commission for Women (NCW) also pointed out that there could be no doubt that India is far ahead of a number of countries in terms of women's rights. The survey was similarly rejected by the Centre for the Study of Developing Societies on the grounds that it lacked transparency with respect to sample size and possible selection bias. The report has also been rejected by the Indian government. Union minister Rajyavardhan Singh Rathore criticized the Indian National Congress for using this survey to damage the reputation of the Modi government and that the survey that was based on "perception" and "afar from any solid facts or numbers". Also in 2018, the Supreme Court of India struck down a law making it a crime for a man to have sex with a married woman without the permission of her husband. Prior to November 2018, women were forbidden to climb Agasthyarkoodam. A court ruling removed the prohibition. The steady change in the position of women can be highlighted by looking at what has been achieved by women in the country:   India has one of the highest number of female politicians in the world. Women have held high offices in India including that of the President, Prime Minister, Speaker of the Lok Sabha and Leader of the Opposition. The Indian states Madhya Pradesh, Bihar, Uttarakhand, Himachal Pradesh, Andhra Pradesh, Chhattisgarh, Jharkhand, Kerala, Karnataka, Maharashtra, Orissa, Rajasthan and Tripura have implemented 50% reservation for women in PRIs. Majority of candidates in these Panchayats are women. Currently 100% of elected members in Kodassery Panchayat in Kerala are women. There are currently 2 female chief ministers in India as of Sept 2018. As of 2018, 12 out of 29 states and the union territory of Delhi have had at least one female Chief Minister. The status of women in India is strongly connected to family relations. In India, the family is seen as crucially important, and in most of the country the family unit is patrilineal. Families are usually multi-generational, with the bride moving to live with the in-laws. Families are usually hierarchical, with the elders having authority over the younger generations, and men over women. The vast majority of marriages are monogamous (one husband and one wife), but both polygyny and polyandry in India have a tradition among some populations in India. Weddings in India can be quite expensive.
