ORDER GRANTING SUMMARY JUDGMENT IN FAVOR OF PETITIONER
JAMES JEREMIAH SHEA JUDGE
Summary: Upon order of the Court, the parties simultaneously moved for summary judgment on the issue of whether the 5th or 6th Edition of the AMA Guides applies for purposes of calculating Petitioner's impairment rating.
Held: The 1999 version of the Workers' Compensation Act applies to Petitioner's claim because that was the version in effect on Petitioner's last day of work. Under the 1999 statutes, the correct edition of the AMA Guides to apply is that which was current on the date the injured worker reached MMI.

¶ 6 On February 2, 2009, this Court found Liberty liable for Johnson's occupational disease.
¶ 7 On August 21, 2009, Liberty paid Johnson a 25% impairment award.
¶ 8 Between December 5 and 11, 2012, Dr. Whitehouse issued a 50% impairment rating calculated using the 5th Edition. Liberty denied payment of this impairment ...
