The way the MD consitution is written, only a final approval committee actually enacts the letter of the law going into COMAR.
The General Assembly votes and sends the Act to the releveant state agency for COMAR text write up, the agency writes it up and sends the COMAR text back - not to the entire General Assembly - but simply to the committee empowered to approve the text that will be entered into COMAR. The committee has the power to approve or disapprove any changes the agency sends over.
So, in MD its not actually the General Assembly that writes law, its just that final approval committee - as enshrined in the MD constitution.
The above only happens for emergency regulation entered in COMAR, The regulations in COMAR emergency in nature because MSP did not get them finished in time to become effective when the law took affect, so they did both a regular set of regulation (that took affect in January 2014) and the emergency regulations that had to be approved by the AELR (Joint Committee on Administrative, Executive, and Legislative Review) that we as citizens got to testify at.
As for the regular regulations, the notice gets posted for a reply period to which anyone can reply and make suggestions, and which point the lead agency can accept or reject the suggestions. But, as such, anyone that submitted written suggestions that were not accepted, can then sue that agency over the issue if it does not comply with the law as written by the Legislature.
This is one of the things that is being done in the HQL lawsuit, since MSI and the organizations, submitted written replies to the regular COMAR regulations and some where not accepted, including our opposition to the one shot requirement.
