This bill establishes new restrictions on employment within the District of Columbia government, prohibiting the appointment of individuals who have been finally convicted of a crime of violence or a dangerous crime. All new hires would be required to certify that they do not have such convictions. Furthermore, the bill mandates that any current D.C. government employee with a final conviction for a violent or dangerous crime must be terminated within 90 days of the bill's enactment. These terms, such as "crime of violence" and "dangerous crime," are defined by referencing existing District of Columbia Official Code. In addition to employment restrictions, the legislation also prohibits the D.C. government from entering into contracts with certain vendors. A vendor is considered a "covered vendor" if they, or any of their employees, officers, directors, or controlling owners, have been finally convicted of a crime of violence or a dangerous crime. This prohibition applies to all new contracts, and existing contracts with covered vendors must be terminated within 90 days. The definition of "finally convicted" clarifies that it refers to a conviction where the appeals process is complete or the time for appeal has expired.
