Excerpt: The AARP, the EEOC and interested retirees are waiting to hear from the U.S. District Court for the Eastern District of Pennsylvania whether four is greater than nine or whether nine is greater than four. The district court previously enjoined the EEOC from publishing regulations that would explicitly permit employers to coordinate retiree health care benefits with Medicare eligibility. Those regulations were designed to overturn the Third Circuit's ruling in the Erie County case[.]
