AN ACT TO AMEND TITLES 14 AND 19 OF THE DELAWARE CODE RELATING TO BARGAINING UNITS.

This Act addresses information and access rights relating to bargaining units, which are defined under existing law as groups of public employees designated by the Public Employment Relations Board as appropriate for representation by an employee organization for purposes of collective bargaining. Section 1 of the Act amends the Public School Employment Relations Act in Title 14 of the Delaware Code. It provides that a public employer must provide an exclusive bargaining representative with certain contact information of bargaining unit employees, (i) within 14 calendar days of their hiring and (ii) in January and October of each year, starting in January 2026. In addition, a public employer must allow an exclusive representative to communicate with bargaining unit members using their employer-issued email addresses regarding collective bargaining, the administration of collective bargaining agreements, the investigation of grievances, workplace-related complaints and issues, and internal matters involving the exclusive representative's governance or business. Section 2 of the Act makes these same amendments to the Public Employment Relations Act in Title 19 of the Delaware Code.

AN ACT TO AMEND TITLE 24 OF THE DELAWARE CODE RELATING TO GENETIC COUNSELORS.

Maddy summarySB 70 amends Delaware law to allow licensed genetic counselors to directly order genetic tests, which previously required physician authorization. This change directly affects licensed genetic counselors and their patients in Delaware, streamlining access to genetic testing. The key provision removes the prior requirement that counselors obtain orders from physicians for genetic tests, enabling counselors to make these clinical decisions independently within their scope of practice.

AN ACT TO AMEND TITLE 11 AND TITLE 29 OF THE DELAWARE CODE RELATING TO BIOLOGICAL EVIDENCE.

This Act provides protections and rights to victims of sexual assault by doing all of the following: • Codifying the core sections of Delaware's Sexual Assault Kit (SAK) testing policy, adopted in May 2022. • Enacts the recommendations of the Victims' Bill of Rights Committee (VBR Committee), established under SCR 99, (152nd General Assembly) providing rights to victims regarding information about the location, status, and preservation of biological evidence. These protections and rights for victims of sexual assault are in addition to existing requirements for DNA analysis performed by the Division of Forensic Science (DFS) laboratory under Chapter 47 of Title 29 and the Victims’ Bill of Rights under Chapter 94 of Title 11. Section 1 revises the definitions in Chapter 47 of Title 29 by transferring definitions from § 4713 of Title 29, updating existing definitions, and creating new defined terms that reflect current practices. Section 2 updates existing requirements under § 4713 of Title 29 that apply when the DFS laboratory receives, analyzes, and classifies biological samples and obtains DNA results, by doing all of the following: • Adding the names of the state and federal DNA databases. • Referencing current law-enforcement procedures, including the names of Delaware’s criminal justice case management systems. • Requiring the Department of Justice, or a law-enforcement agency authorized by the Department of Justice, to inform DFS if the investigation has determined that no crime occurred in the case connected to a biological sample that has been submitted. This enables DFS to comply with NDIS policies and procedures related to when DNA results can be included in the National DNA Index System. • Adding the VBR Committee’s recommendations preventing the destruction of biological samples from unsolved sexual assault cases based on the victim’s age at the time of the alleged offense. For adults, these biological samples may not be destroyed until 20 years after the collection of the evidence and if the victim was under 18 years of age, until the victim is 40 years old. • Adding references to the new SAK-specific provisions under § 4713A of Title 29 and § 9403B of Title 11. Section 3 adds additional requirements that apply when the DFS laboratory conducts DNA analysis of SAKs, codifying Section 5 and Section 7 of the existing SAK testing policy. Section 4 adds definitions related to biological evidence to Chapter 94 of Title 11 for the Victims’ Bill of Rights. Section 5 adds the following to the Victims’ Bill of Rights: • Requirements that apply to investigating law-enforcement agencies, codifying provisions in Section 3 and Section 4 of the existing SAK testing policy. • The VBR Committee’s recommendations regarding victims’ rights to information about the location, status, and preservation of biological evidence, such as learning the status and results of DNA testing. Victims of unsolved sexual assault cases have the right to notice before biological evidence is destroyed, to request that this evidence be preserved, and to designate another person to receive information about the status of biological evidence on their behalf. Section 6 updates how victims receive notifications from law-enforcement agencies that are required under the Victims’ Bill of Rights, to allow for implementation of the victims’ rights to information about biological evidence. All of the following changes were recommended by the VBR Committee and are identical to the language in Senate Bill No. 17 (153rd): • Allowing law-enforcement agencies to send notifications electronically. • Providing that victims are responsible for providing a law-enforcement agency with changes to the victim’s contact information. • Allowing a victim to indicate and change their preferred method of contact by law-enforcement agencies, including a preference not to be contacted, and law-enforcement agencies must use the victim’s preferred method of contact when possible. Sections 7 through 9 revise the definitions of “DNA” and “DNA profile” in Part II of Title 11 for criminal procedure so they align with the definitions in Chapter 47 of Title 29. This Act also makes technical corrections to conform existing law to the standards of the Delaware Legislative Drafting Manual.

AN ACT TO AMEND TITLE 2, TITLE 6, TITLE 9, TITLE 10, TITLE 14, TITLE 19, TITLE 20, TITLE 24, TITLE 25, AND TITLE 29 OF THE DELAWARE CODE RELATING TO DISCRIMINATION.

This Act aligns Delaware’s non-discrimination laws. Delaware has several broad laws that prohibit discrimination in public accommodations, housing, employment, and insurance but also has many narrow non-discrimination laws that apply to a specific entity, or type of entity, even though a broad law also prohibits discrimination by that entity. This Act aligns the narrower non-discrimination laws with the applicable broad non-discrimination law by also prohibiting discrimination on any other basis protected under the applicable broad law. Adding the reference to the chapter for the applicable broad law includes all protected classes, definitions, and actions that are currently protected under the broad law or that are added to the broad law in the future. This Act does not make any substantive changes to current non-discrimination laws but is necessary because most of the narrow laws do not contain all of the same protected classes as the broad law that also applies or do not include the definitions of classes that are also in the broad law. These inconsistencies could lead to a misunderstanding by someone reading only an incomplete narrow law, and eventually litigation, about what constitutes illegal discrimination by an entity covered by both the narrow and broad laws. For example: • The non-discrimination provision for the Board of Podiatry under § 506(c) of Title 24 does not prohibit discrimination on the basis of the following classes, for which discrimination is prohibited under Chapter 45 of Title 6: age, marital status, religion, sexual orientation, gender identity, or disability. • Only 4 of the 42 chapters in Title 24 establishing professional licensing boards contain a non-discrimination provision, but this does not mean that the other 38 licensing boards are free to discriminate. Aligning these 4 non-discrimination provisions with Chapter 45 of Title 6 clarifies that Chapter 45 of Title 6 also applies to the 38 professional boards that do not have specific non-discrimination provisions. • For merit system state employees, § 5953 of Title 29 only prohibits discrimination based on race, religion, sex, sexual orientation, gender identity, and housing status but in addition to these classes, § 711 of Title 19 prohibits any employer in this State, including the State, from discriminating in employment based on age, marital status, color, national origin, or disability. • Most of the narrower non-discrimination laws do not include all of the definitions in the applicable broad law. Adding the reference to the applicable broad law incorporates those definitions into the narrower law. For example: 1. All of Delaware’s non-discrimination laws prohibit discrimination based on race and all of the broad non-discrimination laws define “race” as including traits historically associated with race, including hair texture and protective hairstyle. However, very few of the narrower non-discrimination laws include this definition of “race”. 2. Several narrow non-discrimination laws prohibit discrimination on the basis of sexual orientation and gender identity but do not include or specifically reference the definitions of “sexual orientation” or “gender identity” in the applicable broad non-discrimination law. Specifically, this Act revises the following narrow non-discrimination laws to align with the applicable broad non-discrimination law, as follows: To align with the Delaware Equal Accommodations Law, Chapter 45 of Title 6, which prohibits discrimination on the basis of race, age, marital status, creed, religion, color, sex, disability, sexual orientation, gender identity, or national origin by establishments that offer goods, services, facilities, privileges, advantages, or accommodations to the general public, including government agencies: • Transportation networks, § 1917 of Title 2. • Parkland owned by civic associations, § 8110 of Title 9. • Jury service, § 4502 of Title 10. • Private business and trade schools, § 8516 of Title 14. • Delaware Veterans Memorial Cemetery, § 1204 of Title 20. • Board of Podiatry, § 506 of Title 24. • Board of Chiropractic, § 706 of Title 24. • The Board of Medical Licensure & Discipline, § 1713 of Title 24. • Board of Funeral Services, § 3102 of Title 24. To align with the Delaware Fair Housing Act, Chapter 46 of Title 6, which prohibits discrimination on the basis of race, color, national origin, religion, creed, sex, marital status, familial status, source of income, age, sexual orientation, gender identity, disability, or housing status in housing offered for sale, rent, or exchange: • Section 4601 of Title 6, because gender identity is missing from the list of classes protected in the purpose section of Chapter 46 even though gender identity is protected under all of the substantive provisions under that chapter. • Recording of deeds, § 9605 of Title 9. • Residential Landlord-Tenant Code, § 5116 of Title 25. To align with Chapter 46 of Title 6, Subsections (a), (b), and (d) are revised to use the term "familial status" because "familial status" is defined in the Delaware Fair Housing Act to mean a household with children. • The definition of “comparable housing” in § 7102 of Title 25 for the conversion of manufactured home communities. To align with the unlawful employment practices in employment under Chapter 7 of Title 19, which prohibits discrimination in employment on the basis of race, marital status, genetic information, color, age, religion, sex including pregnancy, sexual orientation, gender identity, national origin, housing status, disability, status as a victim of domestic violence, a sexual offense, or stalking, or a reproductive health decision: • New Castle County government, § 1183 of Title 9. • Training and apprenticeship programs, § 204 of Title 19. • Merit System of Personnel Administration, § 5953 of Title 29. • Large public works contracts, § 6962 of Title 29. This Act also clarifies that the definition of “place of public accommodation” in § 4502(19) of Title 6 includes entities and services licensed or regulated under Title 5, Banking. This Act does not make any changes to Title 18 for insurance. This Act also makes technical corrections to conform existing law to the standards of the Delaware Legislative Drafting Manual.

AN ACT TO AMEND TITLE 10 OF THE DELAWARE CODE RELATING TO APPEALS OF COURT DECISIONS ON MOTIONS TO TRANSFER.

Currently, if a child’s criminal case is transferred by the Family Court to Superior Court, or if a child files an application in Superior Court to have their criminal case transferred to Family Court and the Superior Court denies the application, there is no recourse for appeal until the child’s criminal case is finally adjudicated in Superior Court. In State v. Roberts, Del.Supr. 282 A.2nd 603 (1971) the Delaware Supreme Court stated its jurisdiction over such appeals by an accused, may only be by operation of law. This Act permits the child to enter a plea of guilty or nolo contendere and appeal an amenability denial to the Delaware Supreme Court within 30 days of being sentenced by the Superior Court. This Act also prohibits any plea being conditioned on waiving this right of appeal. This Act also clarifies that the Superior Court will not retain jurisdiction over the child if the Supreme Court reverses the Superior Court’s Order. This Act also makes technical corrections to conform with H.B. 115 of the 151st General Assembly, which was enacted into law on November 8, 2021 and prohibited transfers to Superior Court for children under the age of 16 in all but the most serious offenses.
