Kalyani, it really sounds alarming,
But there are no control mechnisms to stop frauds done by either HR or any other person.
There won't be any metrics to measure the frauds instead people are striving hard to measure the process itself though they carry lot of data in hand

, The only thing is we should make the people realise their role & responsibility towards the promises they do when they are offered the Job.
this is the matter of Behaviour which purely depends on the Individual traits & can never be changed or controlled by others.
But company has total right to sue the person for such illegal outcomes.
