in the United Kingdom, rape by one's spouse was recognized by a 1991 House of Lords decision known simply as R v R (1991 All ER 481). Another problem results from prevailing social norms that exist. Thus, if the norms within a society do not see spousal rape as worthy violative of social norms, marital rape laws are unlikely to produce successful prosecutions. For example, in Mali, it is considered unthinkable for a woman to refuse her husband's sexual demands; far from being seen as an act of abuse of a wife, marital rape is seen as an incident provoked by the wife who refused to perform her duty: for instance one survey found that 74% of women in Mali said that a husband is justified to beat his wife if she refuses to have sex with him. Other problems arise from the fact that, in some countries where marital rape is illegal, many people are not aware of the existing laws. In some parts of the world marital rape laws are new and rarely enacted, therefore, some people are not aware of their existence. Alternatively, traditional norms concerning marriage may be deeply rooted in the conscience of the population. Substantial segments of the population may therefore not conceptualize that in any modern views of sexuality, it is wroth to force a spouse to have sex is wrong, much less illegal. For instance, a report by Amnesty International showed that although marital rape is illegal in Hungary, in a public opinion poll of nearly 1,200 people in 2006, a total of 62% did not know that marital rape was a punishable crime: over 41% of men and nearly 56% of women thought it was not punishable as a crime in Hungarian law, and nearly 12% did not know. In Hong Kong, in 2003, 16 months after the criminalization of marital rape, a survey showed that 40% of women did not know it was illegal. A 2010 study in South Africa, (where marital rape was made illegal in 1993), showed that only 55% of respondents agreed with the affirmation "I think it is possible for a woman to be raped by her husband". Although in recent years some countries in Africa have enacted laws against marital rape, in most parts of the continent forced marital sex is not a criminal offense. A 2003 report by Human Rights Watch stated that: "With
