If there isn't any causal relation between the hospital's conduct and the injury, or if they can't get a good malpractice affidavit (don't know their law - but GA requires an affidavit from a practicing physician stating exactly what the doctors did wrong), it goes out on summary judgment.
If it survives S/J, the hospital will settle even if they did nothing wrong. A jury can't be expected to look at a horribly maimed mother and not give her money. This is what we used to call a "seven nuns in a station wagon" case - you're wrong even if you're not wrong.
The case has early settlement written all over it, due to the horrifying damages. Rubenstein is well connected and will have no problem finding someone to submit an affidavit of merit.
