The term in loco parentis, Latin for "in the place of a parent" or "instead of a parent," refers to the legal responsibility of a person or organization to take on some of the functions and responsibilities of a parent. Originally derived from British common law, it is applied in two separate areas of the law.
First, it allows institutions such as colleges and schools to act in the best interests of the students as they see fit, although not allowing what would be considered violations of the students' civil liberties.
Second, this doctrine can provide a non-biological parent to be given the legal rights and responsibilities of a biological parent if they have held themselves out as the parent. 
The in loco parentis doctrine is distinct from the doctrine of parens patriae, the psychological parent doctrine, and adoption. In the United States, the parental liberty doctrine imposes constraints upon the operation of the in loco parentis doctrine.

Had she fallen out of a window at home would she be suing her parents? No.
Parents and those In Loco Parentis have responsibilities but are not to blame for the drunken behaviour of individuals.
This young lady should think of herself as a survivor, not as a victim.
As victims go, she is a victim of her own irresponsible and stupid behaviour.
"She also claims that the window she fell from failed to meet building regulations because it was able to open twelve inches"
it can't be easy to fall out of a window that opens 12 inches.
well the law is the law if it had of only opened 4inches she wouldnt of fallen out of it so i think they are liable.
