Background Facts You Need To Know: TLG has a new client, Clean-n-Shine

(Clean), a commercial cleaning company incorporated and located in Maryland, but doing business in all Mid-Atlantic states. Clean uses its own line of cleaning products and also sells its products to other businesses via the internet.
Recently, the Delaware legislature enacted a law banning all sales and importation, until further notice, of Clean’s Shine It floor cleaner in Delaware. It was discovered that one of the ingredients in Shine It, derived from corn, is contaminated and causes a quick-growing mold to spread on surfaces to which it is applied. The mold can be toxic to humans and can cause damage to floors.
Clean wants to expand its products to sale ShineIt in Delaware. If Clean can sale share Shine it in Delaware, it will increase its income and profits. Clean, therefore, wants to challenge the new law as unconstitutional, and it has consulted TLG for advice.  
Winnie and Ralph ask you to MAKE summary report of relevant constitutional law for a meeting with them and Clean’s owners.
