NLRB v. Jones & Laughlin
- Affecting commerce=anything that burdens or obstructs the free flow of commerce.
- Intrastate activities can be regulated by Congress if they have a substantial relation to/effect on ISC
- First time the substantial relation standard was articulated
- E.g., from this case: the refusal to negotiate with a union could lead to a strike, which would affect ISC; thus it can be regulated by the federal government.
