The latest amendment of the Indian Penal Code concerning rape laws in 2013 claims to be not only gender neutral, but also worded broadly. However, regarding the definition of force and consent, it continues to be ambiguous and fails to address many issues. An example is the exemption from marital rape which assumes marriage to be a generalized sort of consent for a man to have sexual intercourse with a woman whenever he wants. Problems in interpretation of consent also exist in cases in which the defendant and complainant are non-married acquaintances.
