In 1869, Pablo de la Guerra, a Californio landholder who had signed the California Constitution, ran for district judge. His opponents challenged his right to office on the grounds that Congress had failed formally to grant citizenship to de la Guerra or other Californios. In the landmark case of People v. de la Guerra (1870), the California Supreme Court upheld de la Guerra's right to run for public office arguing that when California was admitted as a state former Mexican nationals had become citizens.

Pablo de la Guerra was born in Santa Barbara, where his father was the commandant at the local presidio. Although he was educated at a Catholic school in Monterey, he spent most of his life in Southern California, where he was a state senator and magistrate. During his long career, he was mayor of Santa Barbara, president of the California Senate, Lieutenant Governor, and Judge of the 1st and, after 1863, the 2nd Judicial District. In 1845, Governor Pico, wishing to reward de la Guerra for his public service, granted him a portion of Rancho Nicasio. (The remainder went to John Cooper.) After the Bear Flag Revolt in 1846, de la Guerra resisted U.S. rule, refusing to lower the Mexican flag at the customhouse which he oversaw. However, he later became friendlier to the U.S., serving as a delegate at the California Constitutional Convention in Monterey and rallying Southern California behind the Union during the Civil War. Over two thousand mourners attended his funeral at Mission Santa Barbara in 1875.

DE LA GUERRA FAMILY. Hon. Pablo de la Guerra, ex-lieutenant governor of California, was born in Santa Barbara, November 29, 1819. His father, Don Jose Antonio, was a son of Don Juan Jose de la Guerra, and, following the Spanish custom of adding to the paternal surname the name of the mother's family, he was known as Don Jose Antonio de la Guerra y Noriega. Born March 6, 1779, in Novales, Spain, in 1797 he went to the city of Mexico, where he was employed by his uncle, Don Pedro Noriega, in the mercantile line. In 1801 he arrived in California and settled at Santa Barbara, in whose early history he was destined to become an important factor. He became so large a land-owner that at one time his possessions aggregated two hundred and fifty thousand acres, including the 1017 lowing ranches: San Julian, forty-eight thousand acres; Simi, ninety-six thousand acres; Las Pozas, forty-eight thousand acres (where Santa Paula and other towns now lie); Tapo vineyard, fourteen thousand; El Conejo, twenty-four thousand five hundred, and Los Alamos, forty-eight thousand acres. Nearly all these tracts were stocked with many thousands of cattle, sheep and horses. He owned the de la Guerra gardens, in the center of what is now Santa Barbara. While acting as military governor of Alta California, he resided on the corner of what is now Santa Barbara and Canon Perdido, called "El Presidio," but this place becoming too small for his family, he built the de la Guerra mansion, which is a well-preserved historic house of Santa Barbara. The marriage of the Don united him with Dona Maria Antonia Carrillo, who was born in Lower California, of Spanish descent. In 1810, when Mexico claimed independence, he was appointed Habilitado General from both Californias to the vice-royal government in Mexico, and, starting toward the capital with his family, he was captured at San Blas by the patriots, then in revolt against Spain. Many others were arrested at the same time and a large number were shot, but, he being among the last to be captured, miraculously escaped, saved by the tidings of the approach of the Spanish General Callejas. On joining the Spanish forces he found his wife, who had become separated from him. He also lost a writing desk containing $30,000, but three days later he met a priest whom he knew and who by chance had found and recognized the writing desk. On the delivery of the desk, the owner was pleasantly surprised to find that the money had not been molested. With this sum he bought a vessel and returned to Santa Barbara. In 1811 he was appointed to the command of the troops at San Diego, and there he made his home for some years, In 1817 he was appointed captain of the troops at Santa Barbara and returned thither, which afterward continued his home, with the exception of a brief period spent in Mexico as Habilitado General. Finding that in Santa Barbara there was a scarcity of every convenience of life, he gave his influence toward the development of material resources and the establishing of new industries. Among other things he established an olive oil plant, a flour mill, carpenter and blacksmith's shop, shoe store, bakery, soap factory, general warehouse, and drug and dry-goods store, all of these being in the rear of the mansion, except the soap factory, drugs and dry-goods store, which were within twenty feet of the present city hail. One of the captain's most enjoyable duties was the distribution of soap, gratis, to the Indians and Mexicans, who came each week to receive their allowance, which was given to them with a joke or pleasant remark. Then, too, they often received donations of clothing, blankets, sugar, lard, and other essentials. Over three thousand Indians at one time resided at the mission, and a large number of them were known by name to the captain. Captain de la Guerra died February 1858, at the age of eighty-three, and he and his wife, who had died December 25, 1843, were buried in the same sepulchre under the floor of the old mission church. They were the parents of eight sons and five daughters, and to them they gave every possible advantage. Two sons were sent to the city of Mexico to be educated, one to Chile, South America, and still another to England, while several sons and grandsons were sent to Georgetown, D. C. The eldest son, Jose Antonio, married Dona Concepcion Ortega y Lopez. Juan Jose was graduated from three colleges in England and his early death terminated a career that gave brilliant promise. The other children were Rita de Jesus; Maria Teresa, who married William Hartnell; Raymundo; Maria de las Augustias, who married Manuel Iimeno, secretary of state and provisional governor of Alta California, and after his death became the wife of Dr. James L. Ord, of the United States army; Francisco, who married Ascension Sepulveda and afterward her sister, Concepcion; Pablo; Maria Ana, who married Alfred Robinson, of Boston, Mass.; Joaquin; Miguel, who married Trinidad Ortega de Pico; Antonio Maria, who was captain of a native California cavalry during the Civil war; and Maria Antonia, who married Cesario Lataillade, a native of France, and after his death became the wife of Don Gaspar Orena, a native of Spain. After completing his education in the city of Mexico, Pablo de la Guerra returned to California, and, at the age of nineteen years, he served as collector of customs at Monterey, then, with one exception, the most important office in the state of California. At the age of twenty-eight, March 7, 1847, he married Dona Josefa Moreno, member of an old Spanish family of Monterey. They became the parents of six daughters and one son. The son and three daughters reached maturity; Francisca, widow of Thomas B. Dibblee; Carlos, interpreter, teacher and translator of Spanish; Delfina, and Herminia, widow of Louis E. Lee, of Rochester, N. Y. In 1849 Pablo de la Guerra was a member of the first constitutional convention of California. For several terms, and until 1861, he was a member of the state senate. During the latter year he was elected president of the senate, and, on the election of Governor Downey to the United States senate, the lieutenant-governor became governor, and Senator de la Guerra was promoted to the office of lieutenant-governor, which he filled ably. March 11, 1861, he was admitted as attorney and counsellor of the supreme court. October 21, 1863, he was elected judge of the first judicial district, comprising all of Southern California. He was re-elected in 1869 to serve another term of six years, but in 1873 his health became so seriously impaired that he resigned the office. He died February 5, 1874, in Santa Barbara, and was interred in the family sepulchre at the Mission Church. Personally he possessed a high sense of honor, great dignity of bearing, and a marked consideration for others. Courteous to all, his friends were many and his influence great.
