Briefly describe the scope and type(s) of discovery available (e.g., depositions, interrogatories, etc.):
"After a petition is filed, all parties must, upon request of the Regional Director, furnish the Regional Director and serve all parties affected by issues raised in the petition with information concerning parties, issues, and agreements raised in or affected by the petition." 5 CFR 2422.15(a)
It is not true discovery in the civil litigation sense but information sharing. The process is not adversarial.
