430 CMR 4.05 governs the Massachusetts Division of Unemployment Assistance in its administrative cooperation with other States adopting a similar regulation for the payment of benefits to interstate claimants.
Agent State means any State in which an individual files a claim for benefits from another State. Benefits means the compensation payable to an individual with respect to his unemployment, under the unemployment insurance law of any State.
Liable State means any State against which an individual files, through another State, a claim for benefits.
Interstate Benefit Payment Plan means the plan approved by the Interstate Conference of Employment Security Agencies under which benefits shall be payable to unemployed individuals absent from the State (or States) in which benefit credits have been accumulated.
Interstate Claimant means an individual who claims benefits under the unemployment insurance law of one or more liable States through the facilities of an agent State. The term "interstate claimant" shall not include any commuter provided, however, that the Massachusetts Division of Unemployment Assistance may, by arrangement with any adjoining State employment security agency, treat certain commuters as interstate claimants if they reside in geographical areas from which the Massachusetts Division of Unemployment Assistance finds that requiring commuters to file their benefit claims in the State of their last employment would cause undue hardship to such claimants. The term "commuter" applies to each individual who, before becoming unemployed, customarily commuted from his/her residence in the agent State to his work in the liable State. State includes the District of Columbia and Puerto Rico.
Week of Unemployment includes any week of unemployment as defined in the law of the liable State from which benefits with respect to such week are claimed.
