An employee who has filed, and established, a first claim for benefits under the provisions of the Temporary Extended Unemployment Compensation Act of 1961, may not thereafter establish a claim under this section, and an employee who has registered for, and established, a claim under this section may not thereafter establish a claim under the provisions of the Temporary Extended Unemployment Compensation Act of 1961.
