Ratcheting up the stakes in Miami-Dade's hospital wars, Jackson Health System has filed two petitions with the state demanding a hearing to consider its belief that the license for trauma operations at Kendall Regional Medical Center was granted illegally and should be revoked. Jackson, which for years has had the county's only trauma center, has been complaining loudly since the Scott administration decided the state needed more centers. Kendall Regional's opened in November 2011.
