Nikephoross narrative picks up once more during the reign of Emperor Constantine X Doukas (); in 1061 he was made "doux" of Thessalonica by Constantine, and ordered to settle complaints in the theme. The first complaint was a dispute between the Iveron Monastery of Mount Athos and the Byzantine government, centered on the government confiscation of some of the monastery's property and "Paroikoi" (Byzantine serfs), which the monastery viewed as unlawful. Nikephoros sent Michael the "spatharokandidatos" to inquire into the case, before ruling that, based upon a chrysobull issued by Basil II which had declared that the monastery's property and "Paroikoi" were exempt from taxes, they could not be confiscated by the government. Nikephoros settled another dispute in February 1062, this time between the Monastery of Lavra and Theodoros of Aichmalotou, a local landowner, over monastic property; Nikephoros ruled in favor of the monastery. Nikephoros settled a dispute between the Iveron Monastery and the Bishop of Ezoba regarding the boundaries between the lands of the monastery and the lands of the bishop, basing his ruling on the knowledge of the local populace. The last Thessalonian dispute which Nikephoros ruled in was between the Iveron Monastery and the "metochion" of Melissourgeion; the "metochion" appears to have ignored a ruling previously made by Empress Theodora Porphyrogenita, which Nikephoros reasserted.
