alito's opinion distinguishes griswold et al from roe, but i realize that may not be any comfort. and, just a reminder, this is a draft brief from february which will be changed and may not end up being the opinion at all. if you recall, in 1992 kennedy changed his mind at the last second or else roe would have been overturned then.
the "right to privacy" can be quite vague and hard to pin down.
