The law or the penal code of the country must be amended to bring in protection to the maids. As the same is a derivation of the Shariah, I do not think this has been addressed well. That is the root of the problem so let's not beat around the bush!

Has anyone out here read the local penal code? If so, please tell me that there is a law by which the abusive master of a maid can be punished based on the maid's version of the story and some evidence of abuse, like burn marks or bruises?

Investigation of such a case is impossible as the maid is the only one who is defending herself and all the rest in the family are on the other side. So, tell me what would be the outcome of an investigation?
