2642. Obedience to Tax Laws.—Obedience to just laws is owed either from legal justice alone, or also from commutative justice with the burden of restitution. There are various opinions about the case of tax laws.
(a) According to the traditional opinion, the obligation is one of commutative justice, because there is an implicit contract between the government and the people, in virtue of which the former is bound to provide for the safety of the people at home and abroad and to secure those things that are necessary for the common welfare (such as roads, postal service, etc.), while the latter are bound in return to pay the expenses of the government.
(b) According to a recent opinion, the obligation is one of legal justice only, because the imposition of taxes is an exercise of authority by the government, and taxes themselves have the character of a tribute from the part to the whole rather than of a wage or payment. Hence, though he who evades taxes is not held to restitution, he sins against justice, and sins gravely if the matter is considerable.
(c) According to other opinions, tax laws oblige sometimes from legal, sometimes from commutative justice. Thus, some admit that in feudal times there was a contract between the governed and the ruler, and therefore an obligation of commutative justice to give services and taxes; but in modern times they say there is no such contract, and the duties of ruler and subjects rest on natural law and legal justice, not on any compact. Others again distinguish between the obligation before the quota has been determined, which is the duty of legal justice to declare properly the value of one’s property, and the obligation after assessment, which is a duty of commutative justice to pay just tax bills.
2643. The Duty of Exercising the Electoral Franchise.—(a) There is a grave duty of using the privilege granted to citizens of voting in public elections, and especially primaries; for the welfare of the community and the moral, intellectual and physical good of individuals depend on the kind of men who are nominated or chosen to rule, and on the ticket platforms voted for. Hence, those who neglect to vote cooperate negatively with a serious harm (viz., evil in power), or at least with public unconcern about public matters—for example, those who neglect through laziness or indifference to condemn by their vote. A grave inconvenience (e.g., sickness, ostracism, exile, persecution), but not a slight inconvenience (such as loss of time, trouble, ridicule), excuses from the duty; for an affirmative law has exceptions. Neither is there an obligation to vote when an election is a mere formality, as when there is but one candidate or party.
(b) The duty is not one of commutative justice, as the ballot is either a privilege, or a thing commanded by authority, but not a service to which the citizen has bound himself by contract or office. The obligation is, therefore, one of legal justice, arising from the fact that the common weal is everybody’s business and responsibility, especially in a republic. Hence, representatives of the people who by abstention from voting cause a serious damage which they were bound _ex officio_ to prevent, are guilty of commutative injustice and are held to restitution; but a citizen who stays away from the polls sins, and perhaps gravely, against legal justice, though there is no duty of restitution for the damages that result. Moreover, in a general election the vote of one citizen is usually not of decisive influence, and citizens do not make themselves responsible for all the acts of their representatives.
2644. Manner of Voting.—(a) Object.—It is not necessary to vote for the best candidate, provided one votes for a person who is fitted by character, ability, record, experience, etc. for the office, and gives indications, not merely promises, that he will serve the community well. But in certain ecclesiastical elections the voters must take oath beforehand to vote, not only for a worthy candidate, but also for the person whom they honestly think, all things considered, most worthy. In minor offices (such as constable or town clerk) it suffices that the candidate be known as conscientious; but in major offices (such as President, governor, congressman, legislator, or judge) the party principles for which he stands have to be considered chiefly. _Per accidens_, it is lawful to vote for an unworthy candidate when this is necessary to prevent a greater evil, as when the opposing candidate is much worse, or a good ticket cannot be elected unless some less worthy candidates are included.
(b) Purpose.—The end which the voter should have in mind is the good of the public, and hence it is not right to vote for candidates solely or chiefly because they are personal friends, members of one’s own race, organization or religion, or because one wishes to gain favor or escape enmity.
(c) Circumstances.—The voter must avoid all that is contrary to natural law (e.g., selling of votes, repeating, stuffing ballot boxes) or positive law (e.g., state laws require not only citizenship and a period of previous residence, but also other conditions such as registration and freedom from bribery and other election crimes). The opinion that politics is necessarily corrupt, and that all is fair that helps to win, is a false and pernicious doctrine. The conditions for ecclesiastical elections are given in Canons 160 sqq.
2645. Obligation to Seek Office.—A worthy man should run for office in the following case: (a) when the public good calls for his candidacy (e.g., when his election or candidacy will avert serious evils, and there is no one else so available); and (b) there is no grave impediment to his candidacy (such as supremely important private affairs or ill-health that makes it impossible to run).
