III. In the regulation of the agrarian conditions of Africa the statute deals with three kinds of land, (1) private ex iure quiritium,[2390] (2) private ex iure peregrino,[2391] (3) public domain of the Roman people of various sub-classes.[2392] Lastly the statute aims to settle the status of the lands of Corinth.[2393] As regards the Latins and aliens, whatever has already been permitted them by treaty or law is allowed them by this statute, provided the same thing is allowed a Roman citizen; but it is forbidden them if forbidden a citizen. Rights granted the citizens which up to this time are not enjoyed by aliens are not by this law communicated to aliens.[2394] Through this series of reactionary laws, from the Minucian (121) to the Thorian (111), the optimates succeeded in nullifying the good results of the Sempronian agrarian reforms. It was while the Minucian rogation[2395] was under discussion that the senate took advantage of a disturbance in the concilium to arm the consul Opimius with absolute power for putting down C. Gracchus and his followers.[2396] The failure of an attempt in the following year (120) to call Opimius to account for these proceedings established the right of the senate to the appointment of special commissions and to the decretum ultimum[2397]—a right on which the optimates continued to insist to the end of the republic. Through the plebiscite of L. Calpurnius Bestia (also 120)[2398] they put the stamp of legitimacy upon the murder of the followers of Ti. Gracchus by recalling from exile P. Popillius Laenas, who as consul in 132 and head of a special court was chiefly responsible for that judicial crime.[2399] An attempt was made by Q. Servilius Caepio, consul in 106, to restore the courts to the senate,[2400] or possibly to compromise by providing for an album composed of both senators and equites.[2401] The sources imply that the measure was accepted by the comitia; but if so, it must have been immediately annulled, as it was not carried into effect.[2402] Within this period of reaction, and perhaps as a part of it, falls the lex de libertinorum suffragiis of the consul M. Aemilius Scaurus, 115. Although nothing certain is known of it, we may suppose that it attempted again[2403] to restrict the libertini to the four city tribes.[2404] About this time, too, several acts seem to have been passed for diminishing the pay of soldiers, probably undoing the Sempronian law on the subject.[2405]
