Well the age of marriage USED to be 15, but that was abolished, now the age of marriage is puberty, which this country decided was 9.
So yes, a 10 year old girl can be married to a much older man and it would be legal.
This is not a stable country with Human Rights violations. It is also a very, poor country.
The ONLY reason that this termination of marriage was allowed was that the girl was 8 and not 9 therefore she had not reached the "minimum" marriage age of 9.
If she was 9 or 10, then she would not have been granted a termination of marriage, which is different then a divorce. The girl sought out a Judge, to file for her own and plead her own case to terminate the marriage.
