D.C. Mun. Regs. r. 3-3501
Within fifteen (15) days following a request for an exemption, the Director shall conduct an informal hearing.
To obtain an exemption, the requestor shall show, by a reasonable probability, that the disclosure of the names of the members, contributors, and recipients of expenditures shall expose the persons to economic reprisals, harassment, loss of employment, or threat of physical coercion from government officials or private parties.
Evidence of the type of harm alleged, pursuant to § 3501.2, shall include past or present harassment of members, recipients, or contributors due to their associational ties, and/or threats, reprisals, or public hostility toward the minor party, its members, supporters, or individuals representing similar views.
