when the Workers Compensation Carrier, by and through their Attorney filed a Request for Supersedeas with the WCAB they are seeking to avoid payment of whatever monies and/or medical bills were Awarded by the Workers Compensation Judge while there Appeal is pending before the WCAB. This is merely a "preliminary" ruling and may be altered once Oral Argument has been heard, briefs submitted and the WCAB issues its final Opinion and Order.
The phrase that is referenced in your question above means that although the WCAB has Denied the Defendants Request for Supersedeas which essentially Orders the Workers Compensation Carrier to make payments pursuant to the Judges Order, this is merely a preliminary decision and may be altered and/or overruled when the Board issues its final Opinion and Order.
I am assuming from your question that you already have a Attorney to represent your interest in this matter and this question would best be posed of your Attorney. If, however, you are currently unrepresented, it is my recommendation that you contact an Attorney who has been Certified as a Specialist in Pennsylvania Workers Compensation Law for an initial consultation. The Initial Consultation will more than likely be free and any Attorney will accept your case on the Contingent Fee Basis.
This answer to your legal inquiry is based upon the limited facts stated in your question. Accurate legal advice is based upon an exchange between a lawyer and a client. The lawyer can then ask about other facts that may change or confirm the answer. Without that exchange, this reply should be considered limited in value. You should rely on this answer only at your own risk. Direct consultation with a lawyer is always recommended. Answering your question does not create an attorney-client relationship. The answering attorney is licensed in Pennsylvania and all answers are given pursuant to Pennsylvania law, unless otherwise indicated. If you have further questions regarding your issue, or my answer you may contact me to discuss this issue further by calling 215-496-9607 or sending an email to firstname.lastname@example.org
It means that the WC insurance carrier is to pay you based on what is in the WCJ's Order. The Board will decide your claim when they circulate a final Order in approximately 1 year. At that time, they will decide the issue of your average weekly wage, but for now you are winning ...
If you have a lawyer, talk to them about this as they can fill you in on the details that are specific to your claim. If you don't, you should consider getting one.
Best of luck to you!
