Stancill had worked with aluminum ladders for at least seven years prior to the date of the accident. A house painter for two years, he had used them in the exterior painting of more than 50 homes. Ae.App. 47, 48-49. Knowing that as conductors of electricity they could become hazardous, Ae.App. 49, 51, he customarily took precautions against potential shock from overhead power lines. Ae.App. 52-54. Later, Stancill took jobs successively with two companies engaged in the roofing and guttering business, Ae.App. 55, 58, in which metal ladders were used routinely. Ae.App. 56. He worked on more than 100 jobs with aluminum ladders which, at least two-thirds of the time, were 32 feet or longer. Ae.App. 59-61. On each job he would locate the electric service lines and was careful to keep ladders away from them, Ae. App. 56, 61; "[w]e always need to be careful of them," he said, "it was just where they were positioned as to the house as to where to move the ladder — not to come in contact with them." Ae.App. 56. He would also look for the pole-to-pole distribution lines to make sure that they were a safe distance from where he was working. Ae.App. 57, 62. Stancill enjoys perfect vision. Ae.App. 44.
Similarly, Kefauver's "main line of business for seven years was with roofing and guttering." Ae.App. 39. There was no indication that Kefauver had any visual impairment on the date of the accident.

The Itte's hired Capitol Roofing Company, Inc., to perform the work. Capitol subcontracted the job to Kefauver, who employed Stancill to assist him. Ae.App. 63-64.

See note 35 infra.

On the side of the ladder, approximately four feet from the bottom, was a prominent orange, black and white decal warning "DANGER — WATCH FOR WIRES — THIS LADDER CONDUCTS ELECTRICITY." Ae.App. 37, 42, 85. Bracketing the words "THIS LADDER CONDUCTS ELECTRICITY" were orange depictions of lightning bolts. Ae.App. 85. A second decal on the ladder, flagged by the word "CAUTION," provided a guide for positioning the ladder and, at the bottom in bold letters, the admonition "READ ADDITIONAL INSTRUCTIONS ON LADDER." Ae.App. 86-87.

Ae.App. 69, 76.

Ae.App. 76. The line was installed in 1935. Suspended 25 feet above the ground, it was unobscured by structures or foliage, and plainly visible from the area below. Ae.App. 22, 24-25, 26-28. At its closest point to the house, the line had a 7-foot, 5-inch clearance from the left front corner of the roof overhang. Ae.App. 21. After 40 years without apparent mishap, one Wesley Howard brought an aluminum ladder into contact with the distribution line and sustained an electrical shock and injuries. Howard sued Pepco, alleging negligence as the cause of his injuries. The court found that, assuming that Pepco was primarily negligent, Howard was guilty of contributory negligence as a matter of law, and entered summary judgment against him. Howard v. Sylvester, Civ. No. R-78-1851 (D.Md. Dec. 5, 1980), aff'd, 688 F.2d 832 (4th Cir. 1982) (per curiam).

Ae.App. 83. Stancill testified that Kefauver also saw the distribution line. Ae.App. 77.

Because of the fatality, the City of Takoma Park Police Department and the Maryland Public Service Commission investigated. The police found two "fray marks" on the distribution wire at 9 feet, 2 inches from the closest edge of the roof overhang, and 25 feet, 3 inches vertically from the ground. Ae.App. 15, 19. The Commission found no violation of its regulations by Pepco. Ae.App. 92-96. The distribution line, in terms of location and condition, met the Commission's standards, which incorporate those set forth in the National Electrical Safety Code. Ae.App. 92-95, 97.

Joined with Stancill as an appellant is Allyson B. Kefauver, the surviving spouse of John William Kefauver and the personal representative of his estate.

Stancill v. Potomac Elec. Power Co., Civ. No. 80-3160 (D.D.C. Jan. 6, 1982) at 1-2, Appellants' Appendix (A.App.) 186-187.

Discussed infra note 35.

Stancill v. Potomac Elec. Power Co., supra note 13, at 1, A.App. 76.

In diversity cases, federal courts in the District of Columbia apply the substantive law of the forum with respect to those issues that are outcome-determinative. Lee v. Flinkote Co., 193 U.S.App.D.C. 121, 124 n. 14, 593 F.2d 1275, 1278 n. 14 (1979) (explicitly adopting analogously the principles of Erie Railroad Co. v. Tompkins, 304 U.S. 64, 58 S.Ct. 817, 82 L.Ed. 1188 (1938), for federal courts in the District of Columbia). The forum's choice-of-law rules are substantive for Erie purposes, Klaxon Co. v. Stentor Elec. Mfg. Co., 313 U.S. 487, 496, 61 S.Ct. 1020, 1021, 85 L.Ed. 1477, 1480 (1941); Steorts v. American Airlines, Inc., 207 U.S.App.D.C. 369, 372, 647 F.2d 194, 197 (1981); consequently, the District of Columbia rules determine whether Maryland or District of Columbia law governs the instant case. The District of Columbia Court of Appeals has adopted the approach of the Restatement (Second) of Conflict of Laws § 145 (1971) in negligence cases. Myers v. Gaither, 232 A.2d 577, 583 (D.C.App. 1967). Under that section of the Restatement, the court

considers as important contacts, inter alia, the place of the injury, the place where the contract occurred, the domicile of the parties, and the place where the relationship between the parties, and the place where the relationship between the parties is centered. In determining the relative importance of the contacts, the forum will consider the issues, the character of the tort, and the relative purposes of the tort rules of the interested states.

See also Carr v. Bio-Medical Applications, 366 A.2d 1089, 1093 n. 3 (D.C.App. 1976) (approving in negligence case the choice-of-law approach taken in Myers).
Applying these principles, we agree with the District Court, Stancill v. Potomac Elec. Power Co., supra note 13, at 2-3, A.App. 187-188, that the District of Columbia courts would look to Maryland law in this action. Maryland is the place where the accident and the injuries occurred, the domicile of appellants, and the place where the relationship of the parties was centered. Maryland obviously has a strong interest in compliance with its statute, see note 35 infra, and caselaw, see notes 21, 32 infra, concerning conduct relative to electric power lines. No countervailing interest whatsoever of the District of Columbia is apparent.

See, e.g., Myers v. Montgomery Ward Co., 253 Md. 282, 291, 252 A.2d 855, 861 (1969); Aleshire v. State, 225 Md. 355, 365, 170 A.2d 758, 763 (1961); Jackson v. Pennsylvania R.R., 176 Md. 1, 5, 3 A.2d 718, 721 (1939); Ottenheimer v. Molohan, 146 Md. 175, 185, 126 A. 97, 100 (1924); Geiselman v. Schmidt, 106 Md. 580, 584, 68 A. 202, 204 (1907).

See, e.g., Romanesk v. Rose, 248 Md. 420, 425, 237 A.2d 12, 15 (1968); White v. King, 244 Md. 348, 361-362 n. 2, 223 A.2d 763, 771 n. 2 (1966); Bannon v. Baltimore R.R., 24 Md. 108, 124 (1866); Hall v. Hague, 257 A.2d 221, 223 (D.C.App. 1969) (applying Maryland law). Gross negligence is defined as a "`wanton or reckless disregard for human life or for the rights of others,'" White v. King, supra, 244 Md. at 361-362 n. 2, 223 A.2d at 771 n. 2, quoting Johnson v. State, 213 Md. 527, 531, 132 A.2d 853, 855 (1957), including "the omission of that care which even inattentive and thoughtless men never fail to take of their own property." Bannon v. Baltimore R.R., supra, 24 Md. at 124.

Complaint ¶ 13, Stancill v. Potomac Elec. Power Co., Civ. No 80-3160 (D.D.C.) (filed Dec. 10, 1980), A.App. 11.

Gordon v. Maryland State Fair, Inc., 174 Md. 466, 469, 199 A. 519, 521 (1938); Pinehurst Co. v. phelps, 163 Md. 68, 73, 160 A. 736, 738 (1932); Maryland State Fair Agriculture Soc'y v. Lee, 29 Md. App. 374, 378, 348 A.2d 44, 48 (1975). The Maryland Court of Appeals has adopted Professor Prosser's definition of assumption of risk:

In its primary and proper sense, it means that the plaintiff has consented to relieve the defendant of an obligation of conduct toward him, and to take his chance of injury from a known risk. It refers to the situation in which the plaintiff, with full knowledge of the risk, voluntarily enters into some relation with the defendant involving danger to himself through the defendant's conduct. He makes the choice at his own risk, and is taken to consent that the defendant shall be relieved of responsibility. The legal position is then that the defendant is under no duty to protect the plaintiff. It is not a question of any negligence on the part of the plaintiff, who may be acting quite reasonably, and it is immaterial whether he has exercised proper caution.

Bull S.S. Line v. Fisher, 196 Md. 519, 524, 77 A.2d 142, 145 (1950), quoting W. Prosser, Law of Torts § 51, at 377 (1st ed. 1941). See also Hooper v. Mougin, 263 Md. 630, 635, 284 A.2d 236, 239 (1971); Kasten Constr. Co. v. Evans, 260 Md. 536, 544, 273 A.2d 90, 94 (1971); Gibson v. Beaver, 245 Md. 418, 421-422, 226 A.2d 273, 275 (1967).

Harrison v. Montgomery County Bd. of Educ., 295 Md. 442, 451, 456 A.2d 894, 898 (1983); Menish v. Polinger Co., 277 Md. 553, 563, 356 A.2d 233, 238 (1976); Hooper v. Mougin, supra note 20, 263 Md. at 633-634, 284 A.2d at 238; Abraham v. Moler, 253 Md. 215, 218, 252 A.2d 68, 70 (1969); Gutterman v. Biggs, 249 Md. 421, 423, 240 A.2d 260, 261 (1968). Maryland law defines contributory negligence as "`conduct on the part of the plaintiff which falls below the standard to which he should conform for his own protection, and which is a legally contributing cause co-operating with the negligence of the defendant in bringing about the plaintiff's harm.'" Menish v. Polinger Co., supra, 277 Md. at 559, 356 A.2d at 236, quoting Craig v. Greenbelt Consumer Serv., Inc., 244 Md. 95, 97, 222 A.2d 836, 837 (1966). Contributory negligence has often barred recovery in Maryland electrical-shock cases where liability was sought to be grounded on negligence. Frazee v. Baltimore Gas Elec. Co., 255 Md. 627, 632-634, 258 A.2d 425, 427-429 (1969) (house painter, who had warned his crew about hazards of overhead electrical lines, was contributorily negligent as a matter of law when he brought his 30-foot aluminum extension ladder into contact with a high-voltage wire); Driver v. Potomac Elec. Power Co., 247 Md. 75, 81-82, 230 A.2d 321, 325 (1967) (17-year-old, with eighth grade education, whose affidavit stated that he was not aware that power line he saw was conducting electricity, held, on defendant's motion for summary judgment, contributorily negligent when he drove his well-digging rig into power line); Southern Md. Elec. Coop. v. Blanchard, 239 Md. 481, 490-491, 212 A.2d 301, 307-308 (1965) (individual who brought 10-foot television antenna into contact with high-voltage line found, as a matter of law, contributorily negligent). See also State v. Consolidated Gas Elec. Light Power Co., 159 Md. 138, 150 A. 452 (1930); State v. Eastern Shore Gas Elec. Co., 155 Md. 660, 142 A. 503 (1928); Mayor of Cumberland v. Lottig, 95 Md. 42, 51 A. 841 (1902).
Nonetheless, appellants contend that contributory negligence is not available to Pepco as a defense in this case. They argue, Brief for Appellant at 4, that contributory negligence is not a bar to an action, such as this one, which is predicated upon gross negligence. Neither party, however, has directed us to any Maryland case expressly so holding, and our own review of Maryland caselaw might lead us to the conclusion that contributory negligence defeats claims based upon gross negligence, as well as those based upon simple negligence. Indeed, the Court of Appeals of Maryland recently observed that it is "the well-established law of this State that a plaintiff who fails to observe ordinary care for his own safety is contributorily negligent and is barred from all recovery, regardless of the quantum of a defendant's primary negligence." Harrison v. Montgomery County Bd. of Educ., supra note 21, 295 Md. at 451, 456 A.2d at 898. See also Ladnier v. Murray, 572 F.Supp. 544, 547 (D.Md. 1983) (applying Maryland law to the effect that "contributory negligence is an absolute bar to recovery in a negligence case"). Although Harrison indicates that the defense of contributory negligence would be available to Pepco even had it conducted itself in a grossly negligent manner, we need not undertake to resolve the point, or to decide whether Stancill and Kefauver were in fact contributorily negligent. As we now discuss, we find that the record upholds the District Court's dismissal of appellants' action on the basis of assumption of risk.

Motion for Summary Judgment ¶ 3, Stancill v. Potomac Elec. Power Co., No. 80-3160 (D.D.C.) (filed Oct. 30, 1981), A.App. 31. While the efficacy of the defense of contributory negligence to gross-negligence charges may be open to some doubt, see note 21 supra, assumption of the risk under Maryland law indubitably defeats a claim resting upon gross negligence. Once it has been established that the plaintiff assumed the risk, the defendant's negligent conduct, whether characterized as simple or gross, becomes irrelevant. "`In its primary and proper sense, [assumption of the risk] means that the plaintiff has consented to relieve the defendant of an obligation of conduct toward him, and to take his chance of injury from a known risk. . . . The legal position is then that the defendant is under no duty to protect the plaintiff.'" Bull S.S. Line v. Fisher, supra note 20, 196 Md. at 524, 77 A.2d at 145, quoting W. Prosser, Law of Tort, § 51, at 377 (1st ed. 1941) (emphasis supplied). See also Hooper v. Mougin, supra note 20, 263 Md. at 635, 284 A.2d at 239, Kasten Constr. Co. v. Evans, supra note 20, 260 Md. at 544, 273 A.2d at 94; Gibson v. Beaver, supra, note 20, 245 Md. at 421, 226 A.2d at 276.

See note 13 supra and accompanying text.

See Hooper v. Mougin, supra note 20, 263 Md. at 635, 284 A.2d at 239; Kasten Constr. Co. v. Evans, supra note 20, 260 Md. at 544, 273 A.2d at 94; Gibson v. Beaver, supra note 20, 245 Md. at 422, 226 A.2d at 275. Assumption of risk "implies intentional exposure to a known danger, which may or may not be true of contributory negligence." People's Drug Stores v. Windham, 178 Md. 172, 186, 12 A.2d 532, 539 (1940). See also Burke v. Williams, 244 Md. 154, 157, 223 A.2d 187, 189 (1966).

Brief for Appellants at 6-12.

Ae.App. 88-89.

Ae.App. 77. Appellants assert that because Kefauver could not testify, his knowledge of the location of the distribution line is unclear. Brief for Appellants at 11. While our reading of the record dispels any question of Kefauver's actual knowledge, Maryland law imputes that knowledge to one who claims that he did not see an object which, under the circumstances involved, he would have seen had he but used his senses. See, e.g., Fulton Bldg. Co. v. Stichel, 135 Md. 542, 549, 109 A. 434, 437 (1920). So where, as here, actual knowledge of the location of a power line may not be absolutely certain, "the question . . . does not have to rest upon whether or not [the person] had actual knowledge . . . [because] the law rightfully charge[s] him with such knowledge." Southern Md. Elec. Coop. v. Blanchard, supra note 21, 239 Md. at 491, 212 A.2d at 307; see also cases cited therein.

Gibson v. Beaver, supra note 20, 245 Md. at 421, 226 A.2d at 275, quoting W. Prosser on Torts, § 55, at 303 (2d ed. 1955).

Le Vonas v. Acme Paper Bd. Co., 184 Md. 16, 21, 40 A.2d 43, 45-46 (1944) stating:

Electricity is now used so universally . . . that it is a matter of common knowledge that any line carrying electric current is dangerous to a more or less degree. The fact that a wire is charged with electric current is notice of danger, and any person mindful of his safety should treat it with caution. When a person voluntarily touches . . . an electric wire, which he knows, or which a person of ordinary knowledge and experience would have reason to believe, is sufficiently charged with electricity to be dangerous, . . . it will be assumed as a matter of law that his own negligence contributed to the accident.

Accord, Driver v. Potomac Elec. Power Co., supra note 21, 247 Md. at 81, 230 A.2d at 325 (knowledge of danger of electricity will be imputed to most plaintiffs). A very different sort of case was Eastern Shore Pub. Serv. Co. v. Corbett, 227 Md. 411, 423-424, 177 A.2d 701, 707-708 (1962) (plaintiff not charged with knowledge that service wires to unfinished building were alive, where building was supplied with power by a different set of temporary wires, electrical work on building had not yet been completed, and the service wires dangled from the masthead conduit).

Le Vonas v. Acme Paper Board Co., supra note 32, 184 Md. at 23, 40 A.2d at 46. See also Benedetto v. Baltimore Gas Elec. Co., 30 Md. App. 171, 176-178, 350 A.2d 712, 715-716 (1976).

The mere fact that Stancill and Kefauver were pursuing their livelihood is immaterial to the question whether they assumed the risk. In Burke v. Williams, supra note 24, 244 Md. at 158, 223 A.2d at 189, the court held that a deliveryman who was injured when he slipped on an icy walkway while making a delivery acted voluntarily notwithstanding that the walkway was the only means of access to the house at which the delivery was to be made, and despite the claimed economic necessity of keeping his job. It is even clearer that the assumption of risk by Stancill and Kefauver was voluntary, for they could have avoided all danger from the distribution line by the simple expedient of taking statutorily-prescribed precautions. See note 35 infra.

Md. Code Ann. art. 89, §§ 58-63 (1957). A person contemplating the handling or erection of any equipment or apparatus within ten feet of a high-voltage line is required to notify the owner or operator of the line, id. § 61(a); and the latter is then required to take specified precautions, id. § 61(b), which may involve de-energization of the line or installation of physical barriers to prevent contact, id. § 60.

Evans v. Johns Hopkins Univ., 224 Md. 234, 239, 167 A.2d 591, 594 (1961).

The District Court held that Stancill and Kefauver, by ignoring the state's High Voltage Line Act, assumed the risk as a matter of law. Stancill v. Potomac Elec. Power Co., supra note 13, at 1, A.App. 186. Since we conclude that their behavior considered in its entirety constituted an assumption of the risk, we do not reach the question on which the District Court's decision pivoted.
