Reasoning or argument that is compelling or convincing.
Curtis Cannon served discovery requests on Citadel Security but received incomplete responses. In his motion under Rule 37, Cannon included a detailed certification showing his good-faith efforts to resolve the dispute informally. The court found his submission contained cogent reasoning that justified granting the order to compel.
Carlos Castillo challenged a municipal ordinance that singled out his religious practices. His brief presented evidence that the law targeted specific rituals rather than serving neutral public-health goals. The court deemed his analysis cogent and held the ordinance failed strict scrutiny.
Cody Callahan's will contained ambiguous language about asset distribution. Christopher Collins offered extrinsic evidence showing the testator's consistent plan to favor one beneficiary. The probate court found Collins's constructional argument cogent and adopted it over competing interpretations.
Carmen Choi sought to testify at trial from another state due to medical restrictions. Her motion detailed the health risks of travel and proposed secure video safeguards. The judge found her showing of good cause cogent and permitted contemporaneous transmission.
Charles Cunningham challenged a state policy that treated male and female applicants differently for public benefits. His brief demonstrated that the classification rested on outdated stereotypes rather than genuine differences. The court accepted his intermediate-scrutiny analysis as cogent and struck down the policy.
Crown Pharmaceuticals employees sought recognition of their out-of-state same-sex marriages for benefit purposes. Their counsel presented historical and doctrinal analysis showing that exclusion lacked legitimate justification. The court described the submission as cogent and granted the requested relief.
The petitioners were fourteen same-sex couples and two men whose same-sex partners were deceased. They lived in Michigan, Kentucky, Ohio, and Tennessee. Those states defined marriage as a union between one man and one woman under their constitutions and statutes. The petitioners filed suits in federal district courts in their home states. They sought marriage licenses or recognition of marriages lawfully performed elsewhere. James Obergefell and John Arthur traveled from Ohio to Maryland to marry aboard a medical transport plane because Arthur suffered from ALS; Obergefell later sought to be listed as surviving spouse on Arthur's death certificate. April DeBoer and Jayne Rowse, Michigan nurses, adopted three children but could not both serve as legal parents under state adoption rules. Army Reserve Sergeant Ijpe DeKoe and Thomas Kostura married in New York before DeKoe's deployment to Afghanistan and later settled in Tennessee. Each district court ruled in the petitioners' favor. The respondents appealed. The Sixth Circuit consolidated the cases and reversed the district court judgments. The petitioners sought certiorari, which the Supreme Court granted. Same-sex couples had begun establishing families after substantial cultural and political developments in the late twentieth century. Earlier litigation had addressed the legal status of gays and lesbians, including challenges that reached the Supreme Court in Bowers v. Hardwick and Lawrence v. Texas.
