Only in Albany can a bill pass the Assembly with overwhelming bipartisan support, be sponsored by a majority of the State Senate, be endorsed by Gov. Andrew M. Cuomo, and yet never come up for a final vote. That happened to Lavern's Law, a bill that would have helped grievously injured victims of medical malpractice have their day in court. This summer, the Senate majority leader, John J. Flanagan, a Republican, wouldn't allow the bill to be voted on, effectively killing it. The bill is named after Lavern Wilkinson, a Brooklyn woman whose curable form of lung cancer went untreated when doctors at Kings County Hospital failed to alert her to a suspicious mass noted on an X-ray taken three years earlier.
