SEC v. Joseph Nantomah et al.

Fabricated: Case Law | Cited 'Goldberg v. 401 North Washakie Venture LLC, 155 F.3d 465 (7th Cir. 2014)'; court found the citation incorrect/nonexistent and noted 155 F.3d 465 corresponds to Condon v.

Coverage Litig.). || Misrepresented: Case Law | Presented 'Sengry v. R.H. Love Galleries, Inc.' rather than the actual Stenger v. R.H. Love Galleries, Inc.; court identified this as a typographical/garbled citation. || Misrepresented: Case Law | Cited 'Hirk v. R-Arch-Roch. Council, Inc., 561 F.2d 619 (7th Cir. 1977)' in place of Hirk v.

Gerou v. George, Whitten, and United States

False Quotes: Case Law | Petitioners quoted Oates v. National Bank as stating banks 'may only deal in negotiable instruments and lawful money'; court found no such quote in Oates (100 U.S. 239 (1879)). || Misrepresented: Case Law | Petitioners attributed to National Bank v. Matthews a statement that banks 'cannot lend their credit to another'; court found the cited case (98 U.S. 621 (1878)) does not contain that statement. || Fabricated: Case Law | Petitioners cited 'Commercial Bank of Cleveland v. Ely (1853)'; court could not locate that case and found the similar Commercial Bank of Cleveland v. Iola, 154 U.S. 617 (1875) does not contain the quoted language. || Fabricated: Case Law | Petitioners repeatedly quoted 'Federal Reserve Bank of San Francisco v. United States (1919)'; court was unable to locate any case with that name or date. || Misrepresented: Case Law | Petitioners cited 'Glover v. Standard Oil Co., 65 N.E.2d 389 (Ind. 1946)' to support that an unrebutted affidavit stands as truth; court traced citation to a different reported opinion which does not support that proposition. || Misrepresented: Case Law | Petitioners cited Bank of Augusta v. Earle and Merchants' Bank v. State Bank as holding a bank that lends credit acts beyond its charter; court found those cases do not hold that proposition. || Fabricated: Case Law | Petitioners cited 'Farmers' & Mechanics' Bank v. Smith (1819)'; court could not locate any such case and noted the closest is an 1821 case that does not support petitioners' claims.

Fabricated: Case Law | Court could not verify the citation; the case 'S.G. v. SafeSport, 74 F.4th 864, 870 (7th Cir. 2023)' does not appear to exist. || Fabricated: Case Law | Court could not locate this district decision; 'Cafasso v. Central Refrigerated Servs., Inc., 486 F. Supp. 2d 1077, 1084 (W.D. Wis. 2007)' does not appear to exist in this district or under that reporter information. || Misrepresented: Case Law | Citation appears misrepresented: the cited case number 'Cressey v. Hamilton, No. 21-CV-2031 (D. Kan. 2021)' corresponds to a different matter in the District of Kansas.
