86 A.2d 407
LUSBY ET AL.
v.
BALTIMORE TRANSIT COMPANY
[No. 91, October Term, 1951.]
Court of Appeals of Maryland.
Decided February 8, 1952.
Rehearing denied March 12, 1952.[*]
The cause was argued before MARBURY, C.J., and DELAPLAINE, COLLINS, HENDERSON and MARKELL, JJ.
L. Wethered Barroll and Lewin Wethered, with whom were Hugo A. Ricciuti and Anselm Sodaro on the brief, for the appellants.
Benjamin C. Howard, with whom was Hamilton O'Dunne on the brief, for the appellee.
MARKELL, J., delivered the opinion of the Court.
These are appeals from judgments for defendant after demurrers to the declarations were sustained. Defendant *285 demurred on various grounds, including res judicata on the basis of Lusby v. Baltimore Transit Co., 195 Md. 118, 72 A.2d 754. Defendant has also moved to dismiss the appeals on that ground.
Lack of merit in a plaintiff's case is not ground for dismissing his appeal  unless and until frivolous appeals shall become so numerous as to cause this court to emulate the Supreme Court practice of dismissing appeals "for want of a substantial federal question" by dismissing appeals for want of any substantial question at all. The defense of res judicata may be raised by special plea or under the general issue, but not by demurrer unless the declaration on its face shows the former proceedings which are set up as res judicata. Burkhouse v. Duke, 190 Md. 44, 47, 57 A.2d 333. A ruling by this court in analogous circumstances indicates that when it clearly appears from the records of this court that the defense of res judicata must eventually prevail, an erroneous ruling sustaining the defense on demurrer to a declaration would not be reversible error. Wilmer v. Placide, 137 Md. 107, 113-114, 111 A. 822.
In the instant cases, on the authority of Lusby v. Baltimore Transit Co., supra, the demurrers were properly sustained, regardless of the defense of res judicata. The instant cases are essentially the same as the former cases. In so holding we do not decide that the defense of res judicata would be, or that it would not be, good. We may say, however, that what was said in Livingston v. Stewart & Co., 194 Md. 155, 163, 69 A.2d 900, 903, and in the authorities there cited, does not mean that any ruling sustaining a demurrer necessarily "does not determine the merits of the case", but "goes * * * to a defect of pleading".
We need not reiterate the reasoning by which in the former cases we held the declarations insufficient, or restate the reasons why we reach the same result in the instant cases. In Livingston v. Stewart & Co. we held in effect that the declaration was insufficient because it did not state ultimate facts which constituted *286 grounds of liability, but attempted to state, very meagrely, evidentiary facts and to obtain on demurrer a ruling as to the legal sufficiency of the evidentiary facts to prove unstated facts which would constitute a ground of liability. In the instant cases the same or worse is attempted. In the former cases we held the facts alleged insufficient as a ground of liability. In the instant cases plaintiffs have not stated different facts but have added a few meagre evidentiary facts, which they say are sufficient to prove unstated facts sufficient to give rise to liability. The result is far removed from the proper sphere of either pleading or evidence, viz., an argumentative reply to this court's opinion in the former cases. In that opinion we undertook to state principles applicable to the case stated, and to make the application to the facts alleged, not a statement applicable only to the most minute allegations in the declaration and to no addition to or subtraction from those allegations, however immaterial the addition or subtraction.
In the former cases the declaration (as particularized by particulars demanded and furnished) alleged that the foreign substance "was plainly visible to him [the bus chauffeur] had he looked". We said, "There is no allegation that he did, in fact, see it." We said the question before us was whether the allegations show "either that the substance was there long enough for the agent of the defendant to notice it, or that it was in such a position that he should have noticed it." Plaintiffs now say they have alleged that the substance was "at a distance not over ten feet from the eyes of, and on the right hand of, the defendant's chauffeur". This is a minutia which we do not think makes our former opinion inapplicable to the instant case.
In our former opinion we said, "There is nothing to show that the operator of the bus had any special duty to look in that direction." There are no facts to show this in the instant cases; only argumentative assertion that the duty existed and an allegation that the substance "had been present upon the floor of said bus during all *287 or a substantial part of a fourteen minute period immediately prior to" plaintiff's injury. We think no such duty arose during "all or a substantial part of fourteen minutes". There are no facts to show "that the operator of the bus had any special duty to look in that direction" in the instant cases; only argumentative assertions, connected with the allegations as to the fourteen minute interval and the ten foot distance. We also said "there is nothing to show that the substance described looked dangerous". Again, there is only argumentative assertion, plus an allegation that the "substance resembling spit or grease" was "in the shape of an ellipse four inches by two inches in size".
All this is neither pleading nor evidence. It is only argument with this court. In its essentials the case is the same. The operator's primary duty was to operate the bus and in so doing watch traffic, not to look at the floor for "grease or spit" ten feet from him, and to discover it within "all or a substantial part of fourteen minutes".
Plaintiffs' counsel commend themselves for not alleging what they know they cannot prove. We do not question the good faith of counsel, but we see no great merit on the score of candor and no practical advantages in obliterating the difference between pleading and evidence or abandoning "issue pleading" for "notice pleading". The evidentiary fragments pleaded are not only minute but highly selective. As we said in Livingston v. Stewart & Co., they never could be found alone, without many other facts which would qualify their legal or evidentiary effect. If plaintiffs cannot directly prove facts which constitute liability, they should allege the ultimate facts they hope to prove indirectly by inference from evidence. The way to determine the legal sufficiency of evidence is at the trial, not by a distortion of pleading.
Judgments affirmed, with costs.
*288 COLLINS, J., delivered the following dissenting opinion, in which MARBURY, C.J., concurred.
In sustaining the demurrers in the former case we held that there was no allegation that the substance was in such a position that he should have noticed it. In the present declaration the direct allegation is made that: "the presence of which substance was plainly visible to said bus driver during the said fourteen minute period." In the former declaration we held: "There is nothing to show that the operator of the bus had any special duty to look in that direction." In the declaration now before the Court it is alleged: "while said bus was stopped and the attention of the said chauffeur not primarily focused on watching traffic, that said chauffeur in the exercise of the care he owed Plaintiffs should have observed the presence of said foreign substance * * *." In the former declaration we held: "there is nothing to show that the actual substance described looked dangerous." Here it is said: "that said substance appeared to be and was dangerous * * * resembling spit or grease in the shape of an ellipse some four inches by two inches in size * * * appeared to be * * * dangerous to passengers on said bus." I think under the cases of Hanway v. B. & O.R.R. Co., 126 Md. 535, 542, 95 A. 160; Topp v. United Rys. & Electric Co., 99 Md. 630, 639, 59 A. 52; and Moore v. American Stores Co., 169 Md. 541, 182 A. 436, the declaration requires an answer and that the demurrers should have been overruled.
Chief Judge MARBURY joins in this dissent.
