Messrs. Wm. R. Harr, of Washington, D. C., and E. J. Foulds and Elmer Westlake, both of San Francisco, Cal., for petitioners. [260 U.S. 205, 206] Mr. Thomas E. Haven, of San Francisco, Cal., for respondent.
Mr. Justice SUTHERLAND, delivered the opinion of the Court.
In 1895 the California Pacific Railroad Company, one of the petitioners, was authorized by the Legislature of the state of California to construct, and did construct, a railroad bridge across the Sacramento river. For some years prior to that time this company had owned and both petitioners had used another bridge situated in the near vicinity. Upon the construction of the new bridge in 1895 the old bridge was abandoned and demolished. The plans and location of the new bridge, so authorized by the Legislature, received the formal approval of the Secretary of War, in conformity with section 7 of the Act of September 19, 1890 (26 Stat. 454), as amended by section 3 of the Act of Congress of July 13, 1892 (27 Stat. 110), subject to the following condition:
The new bridge was finished in 1895 and the destruction of the old bridge was completed early in the following year. The condition imposed by the Secretary of War was fully complied with. Indeed it appears that the piles constituting the piers of the old bridge were cut down 3 or 4 feet lower than was required, to a level with or below the then existing bed of the river.
Subsequent to the removal of the piles the government of the United States constructed a wing dam above and [260 U.S. 205, 207] carried on dredging operations immediately below the bridge, so that the bed of the river was gradually lowered until, in 1918, when the injury in question occurred, the surface of the water was about 7 feet lower than at the time the piles were destroyed, although the depth of the water remained approximately the same with the result that the old stumps protruded several feet above the then existing bed of the river.
There is nothing to indicate that either of the petitioners had actual knowledge of the changed conditions which brought about the protrusion of the old piles above the bed of the river, or any knowledge that these piles were a menace to navigation.
On July 13, 1918, the dredger Thor, owned by respondent, on her way down the river, drifting with the current, struck on one or more protruding stumps, the upper portion of which had been destroyed, with the result that her hull was pierced and she sank.
The respondent filed a libel in the United States District Court for the Southern District of California against petitioners, asking damages for collision, and, after hearing that court dismissed the libel. The Circuit Court of Appeals, reversing the District Court, held that petitioners were liable for this injury, notwithstanding their full compliance with the condition imposed by the Secretary of War, upon the ground that it was reasonably probable in 1895 that the channel of the river would shift and the conditions ensue which brought about the lowering of the river bed, and that, consequently, it was their duty to anticipate and to guard against the effect of these conditions upon the piles and their failure to do so was actionable negligence.
We are unable to agree with this conclusion. By the Act of September, 1890 (26 Stat. 453, 454), Congress inaugurated a new policy of general, direct control over the navigable waters of the United States. The act provided [260 U.S. 205, 208] for the alteration of existing bridges which interfered with free navigation (sections 4 and 5); prohibited the dumping of waste material in such waters so as to obstruct navigation (section 6); made it unlawful to build wharves, piers, and other structures named, without the permission of the Secretary of War, in such manner as to obstruct or impair navigation; or to commence the construction of any bridge over any such waters under any act of a state Legislature until the location and plans therefore had been submitted to and approved by the Secretary of War; or to excavate or fill, or in any manner to alter or modify the course, location, condition or capacity of the channel of said navigable water of the United States, unless approved and authorized by the Secretary of War ( section 7). The amendment of 1892 did not alter section 7 in any respect material to this inquiry.
By this legislation Congress assumed jurisdiction of the subject of obstructions to navigation and committed to the Secretary of War administrative power in so far as administration was necessary. Under section 7, it was not enough for the California Pacific Railroad Company to secure the authority of the California Legislature to build the new bridge; it was necessary in addition to have the location and plans approved by the Secretary of War before the bridge could be lawfully constructed. That the Secretary of War was authorized to impose the condition heretofore quoted does not admit of doubt. The power to approve implies the power to disapprove and the power to disapprove necessarily includes the lesser power to condition an approval. In the light of this general assumption by Congress of control over the subject and of the large powers delegated to the Secretary, the condition imposed by that officer cannot be considered otherwise than as an authoritative determination of what was reasonably necessary to be done to insure free and safe navigation so far as the obstruction in question was concerned. [260 U.S. 205, 209] To hold, as did the Circuit Court of Appeals, that this determination afforded no protection to petitioners, but that they relied upon it only at their peril, we think is a conclusion without warrant. Having complied with the direction of the Secretary, and having no further interest in anything at that point on the river, it seems altogether unreasonable to hold them to an indefinite and speculative responsibility for future changed conditions. The piles had been removed early in 1896, with an overgenerous observance of the directions of the Secretary. As matters then stood, the removal of the piles, so far as they constituted any obstruction or menace to navigation was complete; that they afterwards became an obstruction was due to changes of a most radical character in the channel of the river, brought about, in the main, by the dredging operations of the government itself. Was the petitioner guilty of negligence in not anticipating the effect of these changes, which did not culminate in the conditions complained of until 22 years later? The question must be answered in the negative.
The order of the Secretary of War, directing the removal of the old piles from the bed of the river to the depth there specified was a valid order, since it was the condition upon which his approval of the location and plans of the new bridge was made. The new bridge was in the near vicinity of the old bridge, for which it was, in fact, a substitute. The effect which the continued maintenance of the latter after the completion of the former might have had upon the navigability of the river at that point is not disclosed. The Secretary of War evidently concluded that the situation was such as to require the removal of the old bridge and piles, but not such as to require the removal of the latter beyond the depth fixed by his order. Whether the limitation in this respect was grounded alone upon what the Secretary considered would be sufficient to secure the safety of navigation, or upon the [260 U.S. 205, 210] fact that to leave the stumps in the bed of the river would be of some positive service in stabilizing the shifting bed of the stream, or useful in some other way, does not appear. It was not for the petitioners, however, to question either his reasons or his conclusions. They were justified in proceeding upon the assumption that what the Secretary, in the exercise of his lawful powers, declared to be no obstruction to navigation was in fact no obstruction. The language which this Court employed in Monongahela Bridge Co. v. United States, 216 U.S. 177, 195 , 30 S. Sup. Ct. 356, 361 (54 L. Ed. 435) is pertinent:
See, also, Union Bridge Co. v. United States, 204 U.S. 364, 385 , 27 S. Sup. Ct. 367; The Douglas, 7 Probate Division (1882) 157; Frost v. Railroad Co., 96 Me. 76, 51 Atl. 806, 59 L. R. A. 68; Maine Water Co. v. Knickerbocker Steam Towage Co., 99 Me. 473, 59 Atl. 953; The Plymouth, 225 Fed. 483, 140 C. C. A. 1.
Even if we leave out a consideration altogether the order of the Secretary of War, it is still difficult to see upon what just ground petitioners could be held liable.
The changes which occurred in the bed of the river were not due to natural causes, whose effect could reasonably have been anticipated, but were due to the artificial [260 U.S. 205, 211] operations of the Government the effect of which appeared only after the lapse of a long period of years.
We agree with what was said by the District Court, in deciding the instand case, upon that subject:
The opinion of the Circuit Court of Appeals is that the question of liability was not affected by the fact that the conditions imposed by the Secretary of War were complied with, holding that these conditions or restrictions did not define the measure of liability to third persons rightfully navigating the river, and Maxon v. Chicago & North Western Railway Co. (D. C.) 122 Fed. 555, is relied upon in support of this view. That was a case, however, where a railroad company had constructed a bridge in conformity with the license granted by the War Department. The obstruction which caused the injury complained of consisted of stone and other material thrown into the river by the railroad company at the foot of and about one of the bridge abutments, and extending out into the channel; but it was no part of the bridge structure and was entirely unauthorized. The court held that the tug which collided with the obstruction had a right to the use of the channel to its full width and having no knowledge or warning of the presence of the obstruction was entitled to recover for the resulting injury. The stone and other material were unlawfully thrown into the stream and constituted from the beginning an unlawful obstruction. In the instant case the piles forming part of the old bridge were lawfully placed and lawfully maintained until they were [260 U.S. 205, 212] ordered removed by the Secretary of War. His order for their removal was complied with, and the channel was left by petitioners wholly unobstructed, in law and in fact. The obstruction did not develop until years afterward and was due to causes which they were not bound to anticipate and provide against and for which they were in no degree responsible.
The decree of the Circuit Court of Appeals is therefore reversed and that of the District Court affirmed.
