[6] In the late 1860s he became president of Junta Provincial Católico-Monárquica, emerged as key Carlist theorist[7] and laid out the legal claim of Carlos VII;[8] the pretender rewarded him with the title of Marqués de Comín.

The couple had 3 children: Pascual (born 1855), Francisco Javier (1857)[15] and María Comín y Moya (1862),[16] all brought up in very religious and zealously Traditionalist ambience.

[18] Comín Moya obtained the licenciatura in law in Zaragoza, to pursue his doctoral research at Universidad Central in Madrid later on;[19] the year of his doctorado is not clear.

Already as a 10-year-old boy he was listed in various open letters which supported the Catholic cause;[28] in his teens he delivered addresses during local gatherings and while at the university he engaged in the religious charity organisation Asociación San Luis Gonzaga.

In the late 1870s[30] and early 1880s[31] his name kept appearing among signatories of various declarations of support or protest letters, usually related to religious questions and perceived anti-Catholic measures of the Madrid government.

[46] A royal decree which created a nationwide Comisión General de Codificación nominated him to sub-commission entrusted with work on specific legal Aragón establishments.

The regional jefatura went to the young Duque de Solferino; as he moved to Catalonia the role was then handed to the veteran landowner Manuel Serrano Franquini.

Following his death in 1906[53] the position was vacant; among candidates to take over there was José María del Campo, Cavero's son Francisco and the young Marqués de las Hormazas.

[71] In the mid-1910s Carlism was divided between followers of the theorist Juan Vázquez de Mella and the claimant; the former advocated a grand ultra-right alliance, the latter demanded loyalty based on own monarchic claim.

[72] Moreover, the Mellistas sympathized with Central Powers, the claimant tended to favor the Entente, while the party political leader Marqués de Cerralbo, aging and tired, was unable to take a firm stand.

Comín remained a resolute Germanophile,[73] but he did not encourage the Mellista campaign and maintained loyalty to the claimant, himself incommunicado in sort of a house arrest in Austria.

[74] When the First World War ended in early 1919 Don Jaime travelled to Paris; he immediately dismissed all leadership including Cerralbo's interim successor, Cesareo Sanz Escartín.

[80] In early March he was back in Spain and proceeded to sort out most urgent personal matters; he ceded the Aragón leadership to a collegial makeshift body,[81] set up a new Catalan jefatura[82] and tried to re-organize command layer in other regions.

[88] In the summer of 1919 Comín, apart from his routine professional engagements and work for the Zaragoza ayuntamiento,[89] shuttled across Spain not only to Madrid but also to other regional capitals;[90] moreover, he visited the claimant in France.

[98] Before resignation Comín recommended that his successor as secretario general be Luis Hernando de Larramendi, also a Germanophile and the politician he earlier co-operated with during numerous social initiatives in Zaragoza.

[100] The campaign proved successful and Melgar did not take part in a grand Jaimista meeting dubbed Magna Junta de Biarritz, staged in November 1919; it is not clear whether he was not invited or aware that spirits against him were running high, he withdrew.

He and a group of Basque-Navarrese leaders, including Hormazas, Joaquín Beunza, Tomás Domínguez Arévalo and Julian Elorza Aizpuru, addressed the claimant with a letter.

They declared utter loyalty to the cause and to Don Jaime; nevertheless, in ultimative tone they demanded that “funesta y perjudicial” influence of Melgar and his men be reduced, with specific references to management of El Correo Español.

He went on with his professional juridical duties, either representing clients in private lawsuits[105] or acting as assessor for the Zaragoza ayuntamiento;[106] he might have performed some roles in the city council itself.

His death was acknowledged in merely a handful of newspapers,[110] including few national ones;[111] he was noted as notable Aragón lawyer and former Carlist executive, though some obituaries confused Comín with his brother Francisco Javier.
