from the government's perspective, marriage is legal contract. i donot think i is wise to allow minors to marry (or enter any legal contract). may be we can allow 15 yr olds to marry if they have their consent along with that of their parents. socially and culturally this is delicate issue. i feel that a woman's education and career should not be affected by marriage. she should not be pressurised onto a decision. at 15 she is still a kid. kids should go to school and plan to go to college and have a career. unless in extraordinary circumstances i donot think marriage is appropriate at 15. but then who decides a situation as extraordinary. we cannot have a fixed law on this issue.
