Ordinarily it is the statutory right of a defeated litigant to take an appeal, provided he can state any colorable ground of exception. In some jurisdictions he is required to obtain the approval of the trial court or else of some member of the appellate court. There are many judges who think that such a practice should be universally adopted. It would certainly tend to relieve the dockets of appellate tribunals, and to bring lawsuits to a speedier end. If one were sure that the judge to whom application was made for an approval of the appeal would always act intelligently and impartially, such a precaution against useless litigation would be admirable. But the trial judge is not in a position that naturally leads to an unprejudiced judgment. The appeal is asked on account of mistakes of his, and he will not be apt to think that he has made any. The judge of the appellate court will be impartial and unprejudiced, but he will have a very imperfect knowledge of the case. He could only be asked to make a hasty examination of the points involved, and it would be quite possible for him to reject as frivolous grounds which, on a lengthy investigation after a full argument, might have seemed to him substantial. In view of these objections, and of the unequal attainments and experience of the different judges of our courts, the bar are generally in favor of making appeals a matter of right; and what the bar favors in such a matter the legislature usually enacts. * * * * * The opinions and judgments of all American courts of last resort are officially reported for publication. At first they were not so reported. The earliest volume of American judicial decisions (Kirby's) was published in 1789 as a private venture. A few years later the States began to provide official reporters for their highest courts and soon assumed the expense of publication. There are now more than fifty current sets of federal and State reports, the annual output being about four hundred volumes, containing 25,000 cases. The mere indexing and digesting of these reports for the use of the bench and bar has become a science. While consulted by comparatively few who are not connected with the legal profession, they constitute a set of public records of the highest value to every student of history and sociology.[Footnote: See "Two Centuries' Growth of American Law," 6.] It is the custom to prefix to the report of each case a head-note stating briefly the points decided. Ordinarily this is the work of the reporter. In a few States the judges are required to prepare it; and to do so then naturally falls to the lot of that one of them who wrote the opinion. Occasionally the head-note contains statements not supported by the opinion. In such case the opinion controls unless it is otherwise provided by statute.
