A financial adviser has served a client for several years. When the client informs her that he plans to marry his gay partner and wants to add his future spouse as a beneficiary on his investments, the adviser shows surprise because she had believed that her client was heterosexual. The adviser speaks a hateful insult and informs the client that she will no longer handle his investments. The client turns to a national LGBTQ advocacy group and, with their support, sues the financial advisor for discrimination. On what constitutional basis would the Supreme Court most likely rule in regard to the constitutional rights of the financial adviser and the client? The First Amendment protects individual freedom of expression. The 14th Amendment guarantees equal protection of the laws. Article IV, Section 2, protects all privileges and immunities in several states. The 10th Amendment reserves powers not delegated to the federal government “to the States, or to the people.”
