Feigned Conspiracy Agreement
Beverly proposed diverting scholarship funds to Jacob in a series of emails. Jacob replied with detailed suggestions but later told the dean he had only pretended to agree to create a record.

The Court examined whether those deadlines imposed an unconstitutional burden on Anderson's access rights.
Washington voters approved a blanket primary allowing any voter to select candidates from any party. The Republican Party claimed the system forced unwanted association with candidates it did not endorse. The Court assessed whether the primary format violated the party's associational rights.
