No individual, whether of the same or opposite sex, shall be a Member’s Spouse on account of the fact that such individual has entered into a domestic partnership, civil union or other formal or informal relationship with the Member that is not denominated as a legal marriage under the laws of a jurisdiction, even if those laws provide similar rights, protections and benefits to persons in those relationships as they do to married persons.
