In most countries, there is a legal age limit. In the UK, according to the Sexual Offences Act 2003, it’s a criminal offense for any kind of sexual activity to take place between two people where one or both participants are under 16 and the one who is older would probably be jailed.
However, the underlying purpose of the law is to protect underage teenagers/children from sexual predators and in case both the participants are under the age of 16; they will be apprehended but chances are that they will get away with a reprimand and their parents will be informed.
In the Sindh province, it is illegal for anyone to get married under the age of 18. These girls are residents of Sindh province; hence, irrespective of the fact that the girls willingly ran away with the grooms, legally a 14 or 16-year-old girl marriage is null & void. If you do not believe in the law of the land then there is no argument believe what you will.
I am sure that most honorable members would have 14 /16-year-old sisters, daughters or nieces, do you honestly believe that a 14 or even 16-year boy or girl is capable of making correct decisions especially the ones affecting the rest of his/her life?
