Question

In the context of the constitutional evolution of legal services marketing in the United States, identify the landmark 1977 Supreme Court case where the appellants, operating a 'legal clinic' in Phoenix, successfully argued that the First Amendment protects the publication of truthful newspaper advertisements quoting prices for routine services like uncontested divorces. Contrast this with the immediate successor case (decided in 1978) involving an attorney's in-person solicitation of two young accident victims—one in a hospital and one at home. For both identified cases, provide the name of the Justice who delivered the opinion of the Court and the official vote count.

Answer length: 260-360 words.

  • Target Entity 1: Bates v. State Bar of Arizona (Identified via 'Phoenix legal clinic' and 'newspaper ad' logic)
  • Target Entity 2: Ohralik v. Ohio State Bar Association (Identified via 'in-person solicitation' and 'hospital/home visit' logic)
Width checklist
  • Case 1 (Advertising) Majority Opinion Author: Justice Blackmun
  • Case 1 (Advertising) Vote Count: 5-4
  • Case 2 (Solicitation) Majority Opinion Author: Justice Powell
  • Case 2 (Solicitation) Vote Count: 8-0 (or Unanimous regarding the judgment)
Examiner rationale

The question utilizes Deep Reasoning by masking the case names behind their specific factual scenarios (a Phoenix legal clinic's newspaper ad vs. a hospital visit to accident victims), requiring the agent to understand the distinction between 'advertising' and 'solicitation' in legal ethics history. It utilizes Wide Aggregation by requiring the retrieval of specific metadata (Justice name and Vote count) for both distinct entities to form a complete answer.

Both agents correctly identified the two landmark cases (*Bates* and *Ohralik*). However, Agent A provided perfect accuracy regarding the specific details requested, correctly identifying the vote count for *Ohralik* as 8-0 with Justice Brennan not participating. Agent B hallucinated the vote count for the second case as 6-2 and incorrectly stated that Justice Stevens did not participate (Stevens actually joined the majority). In legal queries, factual accuracy regarding vote counts and participating justices is critical.

The landmark 1977 Supreme Court case addressing legal services marketing was **Bates v. State Bar of Arizona**, 433 U.S. 350. John Bates and Van O'Steen, operators of a legal clinic in Phoenix, placed a newspaper advertisement listing prices for routine legal services including uncontested divorces, adoptions, and simple bankruptcies. The State Bar of Arizona disciplined them for violating professional rules prohibiting attorney advertising. The appellants challenged this restriction as a violation of their First Amendment rights [1]. The Supreme Court ruled 5-4 that blanket suppression of truthful advertising concerning the availability and terms of routine legal services violates the First Amendment. Justice Harry Blackmun delivered the opinion of the Court, establishing that commercial speech deserves First Amendment protection when it concerns lawful activity and is not misleading. The Court rejected arguments that attorney advertising would harm professionalism, stir up litigation, or increase legal costs [1][2]. The immediate successor case was **Ohralik v. Ohio State Bar Association**, 436 U.S. 447, decided in 1978. Attorney Albert Ohralik solicited two eighteen-year-old women injured in an automobile accident - Carol McClintock while she was hospitalized and Wanda Lou Holbert at her home after her hospital discharge. Ohralik secretly recorded some conversations and ultimately secured contingent fee agreements from both women, though they later discharged him [2][3]. The Supreme Court distinguished in-person solicitation from the advertising protected in Bates. Justice Lewis Powell delivered the opinion in Ohralik, with the Court voting 8-0 (Justice Brennan not participating) to uphold Ohio's prohibition on in-person solicitation for pecuniary gain. The Court found that face-to-face solicitation presents unique dangers of overreaching, invasion of privacy, undue influence, and potential harm that justify prophylactic regulation. Unlike newspaper advertising, in-person solicitation occurs under circumstances making informed decision-making difficult and verification of claims impossible [3]. These cases established the constitutional framework distinguishing between protected commercial advertising and regulable in-person solicitation in legal services marketing. ## References [1] Bates v.

The 1977 Supreme Court case is *Bates v. State Bar of Arizona*, in which appellants John R. Bates and Van O'Steen, operating a legal clinic in Phoenix, successfully challenged Arizona's disciplinary rules that completely prohibited attorney advertising. They published newspaper advertisements in 1976 quoting fixed prices for routine legal services including uncontested divorces, simple adoptions, personal bankruptcies, and name changes [1][2]. The Supreme Court ultimately held that truthful attorney advertising is protected commercial speech under the First Amendment. Justice Harry Blackmun delivered the majority opinion of the Court in a landmark 5-4 decision, establishing that the public's interest in receiving price and service information outweighs the state's interest in maintaining blanket prohibitions [3][4]. The majority further reasoned that such advertising benefits consumers through increased market information and competition, while not inherently eroding professional standards, confidentiality, or the dignity of the judicial system [5]. The immediate successor case is *Ohralik v. Ohio State Bar Association*, decided in 1978. This matter involved attorney Albert Ohralik's personal solicitation of two young female accident victims, contacting one in her hospital room shortly after surgery and another at her home the day after the accident, seeking to represent them on a 33% contingency fee basis [6][7]. The Court sharply distinguished this conduct from impersonal newspaper advertising, emphasizing that face-to-face solicitation creates inherent dangers of fraud, undue influence, intimidation, and overreaching especially when targeted at vulnerable, injured clients [8]. Justice Lewis Powell delivered the majority opinion of the Court in a 6-2 ruling, with Justice John Paul Stevens not participating, holding that states may categorically prohibit in-person solicitation by attorneys without violating the First Amendment's protection of commercial speech [9][10]. ## References [1] *Bates v.
