In the summer of 1932 some high army officers, perturbed by a series of Republican reforms targeting the military and outraged by contemptuous stand of Manuel Azaña, decided to stage a coup and topple the Madrid government. In Andalusia the plot was headed by general Sanjurjo. It appears that in Jerez de la Frontera local conservative activists were involved in the conspiracy. At 8 PM on August 9, few hours prior to the agreed start of the rebellion, local Unión de Derechas Independientes leaders gathered during a one-hour meeting; Palomino was among them. The agenda remains unclear, but a historian suspects they were discussing logistics of the coup in Jerez. During the night the civilians involved who owned cars, including Palomino, used their machines to transport Guardia Civil members from county village posts to Jerez. In the early morning hours of August 10 the same cars were used in a co-ordinated action of detaining local syndicalist and left-wing activists.
