Del. Code Ann. tit. 18, § 3008
The Commission shall promulgate reasonable rules, including uniform standards, and operating procedures in order to effectively and efficiently achieve the purposes of this Compact. Notwithstanding the foregoing, in the event the Commission exercises its rulemaking authority in a manner that is beyond the scope of the purposes of this chapter, or the powers granted hereunder, then such an action by the Commission shall be invalid and have no force and effect.
Rules and operating procedures shall be made pursuant to a rulemaking process that conforms to the Model State Administrative Procedure Act of 1981 [15 Uniform Laws Annotated p. 1 et seq.] as amended, as may be appropriate to the operations of the Commission. Before the Commission adopts a uniform standard, the Commission shall give written notice to the relevant state legislative committee(s) in each compacting state responsible for insurance issues of its intention to adopt the uniform standard. The Commission in adopting a uniform standard shall consider fully all submitted materials and issue a concise explanation of its decision.
A uniform standard shall become effective 90 days after its promulgation by the Commission or such later date as the Commission may determine; provided, however, that a compacting state may opt out of a uniform standard as provided in this section. “Opt out” shall be defined as any action by a compacting state to decline to adopt or participate in a promulgated uniform standard. All other rules and operating procedures, and amendments thereto, shall become effective as of the date specified in each rule, operating procedure or amendment.
(d) Opt out procedure. —
If a compacting state elects to opt out of a uniform standard, the uniform standard shall remain applicable in the compacting state electing to opt out until such time the opt out legislation is enacted into law or the regulation opting out becomes effective. Once the opt out of a uniform standard by a compacting state becomes effective as provided under the laws of that state, the uniform standard shall have no further force and effect in that state unless and until the legislation or regulation implementing the opt out is repealed or otherwise becomes ineffective under the laws of the state. If a compacting state opts out of a uniform standard after the uniform standard has been made effective in that state, the opt out shall have the same prospective effect as provided under § 3015 of this title for withdrawals.
If a compacting state has formally initiated the process of opting out of a uniform standard by regulation, and while the regulatory opt out is pending, the compacting state may petition the Commission, at least 15 days before the effective date of the uniform standard, to stay the effectiveness of the uniform standard in that state. The Commission may grant a stay if it determines the regulatory opt out is being pursued in a reasonable manner and there is a likelihood of success. If a stay is granted or extended by the Commission, the stay or extension thereof may postpone the effective date by up to 90 days, unless affirmatively extended by the Commission; provided, a stay may not be permitted to remain in effect for more than 1 year unless the compacting state can show extraordinary circumstances which warrant a continuance of the stay, including the existence of a legal challenge which prevents the compacting state from opting out. A stay may be terminated by the Commission upon notice that the rulemaking process has been terminated.
