In the case of California v. Washington (1958), the Supreme Court was asked to resolve a dispute between two states over their respective rights to tax income earned by an individual who lived in one state but worked in another. The plaintiff, California, argued that it had the right to tax all of an individual's income if they were domiciled there, even if some or all of that income was earned out-of-state. On the other hand, Washington contended that it had a right to tax any and all income earned within its borders regardless of where the earner resided. The court ruled in favor of Washington stating that while both states could impose taxes on such individuals' incomes without violating constitutional principles against double taxation; each state must provide credits for taxes paid elsewhere so as not to burden interstate commerce unfairly. This decision established important precedent regarding how states can levy personal income taxes on nonresidents and residents alike who earn money across state lines.

In the dissenting opinion for California v. Washington, it was argued that the Supreme Court should not have jurisdiction over this case as it is fundamentally a political issue rather than a legal one. The dispute between California and Washington regarding their respective rights to fish in interstate waters falls under the purview of Congress, which has been granted power by the Constitution to regulate commerce among states. It was also noted that there are existing federal laws and treaties governing fishing rights in these areas, further emphasizing that this matter should be resolved through legislative action rather than judicial interpretation. Additionally, it was pointed out that allowing such cases could open up floodgates for other states to bring similar disputes before the court instead of seeking resolution through negotiation or congressional action - an outcome deemed undesirable due to potential strain on court resources and disruption of established processes for resolving interstate conflicts.
