(b) The legal requisites for practising as a lawyer vary with the place or government. In Canon Law, it is necessary that an advocate be a doctor or expert in ecclesiastical jurisprudence, that he be twenty-one years of age, duly approved, etc. (see Canons 1657 sqq.).
1997. The Duties of a Lawyer in Introducing Cases.—(a) He may not stir up litigation, as a means of bringing himself occupation and gain. The Catechism of the Council of Trent, Translated into English with Notes (Joseph F. Wagner, Inc., New York City, 1923), p. 475, denounces this practice as among the chief violations of the Tenth Commandment. Among lawyers it is regarded as unprofessional, and at common law it is an indictable offense.
(b) A lawyer may not take or assist an unjust cause—one, namely, that is in opposition to moral or positive law, as when a party comes to him with the request that he conduct a spite case whose purpose is to harass or oppress an innocent person. He who defends injustice is a cooperator, and is therefore guilty (see 1779). But if a case has a good foundation in law, the lawyer is not bound to inquire into the subjective dispositions or the conscience of the client in the matter, and he may take the case even though he does not know that the client is in good faith.
(c) A lawyer should not refuse a just cause, merely because the person he is asked to assist is indigent or not in favor. Commutative justice does not oblige him to offer his services to one in need of them; but there is a duty of legal justice to give his best efforts if he is appointed as counsel for a poor person, and also at times a duty of charity to do this if he is asked for legal help by one who is in need.
1998. The precept about works of mercy, being affirmative, does not oblige for every instance, but only when the due circumstances of time, place, opportunity, etc., are present. Hence, a lawyer is not obliged by charity to devote himself to every deserving case that is presented to him (see 1227). (a) Thus, as to place, charity does not require that one go about looking for the needy, but that one help those who are at hand. (b) As to time, charity does not require that one take care of future needs, but that one help those who are in present distress. (c) As to persons, charity does not require that help be given to all alike, for some have a greater claim on one’s charity than others (I Tim., v. 8). (d) As to need, charity does not command that help be given those who can easily help themselves, or who can obtain it from third parties who are better fitted to bestow it.
1999. Charity does not oblige to works of almsgiving, if the inconvenience to the donor is out of proportion to the distress from which the donee is rescued (see 1158). The inconveniences that correspond with the various degrees of distress are thus explained by theologians:
(a) if distress is extreme (e.g., a prisoner is about to be sentenced to death unjustly), a proportionate inconvenience is, according to some, a grave loss, or, according to others, the loss of at least a part of the necessaries of one’s state (see 1231, 1251);
(b) if distress is very grave or grave (e.g., an accused man will be sentenced unjustly to a long and harsh imprisonment), the loss of goods without which one’s state of life cannot be maintained so becomingly is, according to one opinion, not excessive; but, according to another view, any notable loss or inconvenience is excessive;
(c) if distress is ordinary (e.g., an accused will be unjustly sentenced to a small fine), the loss of goods that are purely superfluous is, according to some, a proportionate inconvenience, but others think that only such assistance need be given as will cause no inconvenience whatever, such as advice or other service given during spare times.
2000. When Is a Cause to Be Regarded as Unjust?—(a) In civil cases the suit or defense is unjust when it clearly has no moral right. A lawyer who recommends litigation in a case of this kind is unjust to the adverse party, if that party loses; he is unjust to his client, if the client loses and is thus put to unnecessary expense. Generally speaking, a Catholic lawyer ought not to accept a divorce case. The lawyer’s position is different from that of a judge. Occasionally a judge cannot refuse a case without serious inconvenience to himself (see 1949, 1997); the lawyer, however, is free to accept or refuse these cases. The general prohibition is founded on the fact that in this country most divorce cases are means to an invalid remarriage. Some theologians argue that since it is the remarriage, not the divorce, that is intrinsically evil, a lawyer might accept a divorce case for a very grave reason, e.g., to relieve desperate financial conditions. In practice, however, owing to the danger of scandal, the exception would be rare. Exceptions which are possible include cases where divorce is sought for a marriage that is invalid _coram ecclesiam_, e.g., civil marriage of Catholics, or simply for the settlement of civil effects Where no danger of remarriage is involved. In all cases involving Catholics, the lawyer should bear in mind the necessity imposed upon Catholics by the Third Council of Baltimore to consult ecclesiastical authorities before seeking civil separation from bed [and board.]
