State Scrap Purchase Program
The State of Maryland operated a program buying abandoned cars for scrap. It paid higher prices to in-state owners than to out-of-state sellers. Because the state acted as a particeps in the market rather than as a regulator, the price differential did not violate the Dormant Commerce Clause.
Timber Sale With Processing Condition
Alaska sold state-owned timber at auction. It required buyers to process the timber inside the state before export. The downstream restriction exceeded the state's role as a particeps in the initial sale and therefore violated the Dormant Commerce Clause.
A city funded its own construction projects and required contractors to hire a percentage of city residents. Acting as a particeps by funding the projects directly, the city could impose the residency preference without violating the Commerce Clause.
Mediation Communication Privilege
During mediation a nonparty witness supplied documents. As a particeps the witness could refuse to disclose and prevent others from disclosing that participant's own mediation communications under the Uniform Mediation Act.
Nonparty Participant Definition
A consultant attended mediation sessions to advise one side on technical issues. The consultant qualified as a particeps and therefore enjoyed the nonparty participant privilege to withhold its own communications.
Waiver Of Nonparty Privilege
After mediation a party sought to compel the nonparty expert's testimony. The particeps could still assert the privilege because it had not expressly waived protection of its own mediation communications.
