The Robert Taylor / Dechmont Law Incident under-corroborated
On 9 November 1979 a sober, well-regarded Scottish forestry worker reported being
attacked near Livingston by spiked spheres deployed from a large domed craft;
genuine physical traces (ground marks, torn trousers) led police to log it as a
criminal assault — making it the UK's only UFO case formally investigated by
police, though it remains a single-witness event with no corroboration of the
craft and a leading prosaic explanation (an epileptic episode) that is plausible
but unproven.
Dechmont Law is the corpus's cleanest study of PHYSICAL TRACE plus UNIMPEACHABLE
WITNESS minus CORROBORATION: the aftermath (torn trousers, ground marks, a
sincere teetotal witness, a police assault file) is unusually well-documented,
while the craft and the rolling 'mine' spheres rest on one observer with no second
witness, photograph, or material. It is 'Scotland's Socorro' — a daylight
landing-and-trace case — and a textbook test of how far solid documentation of the
aftermath can carry a claim the phenomenon itself leaves uncorroborated.
Timeline
1979-11-09T10:00+0000
Robert Taylor, walking his dog in a forestry clearing on Dechmont Law, reports a
large domed dark/metallic sphere; two spiked spheres 'like naval mines' roll out,
grab his trouser legs, an acrid smell overwhelms him, and he loses consciousness.
witnesses: Robert Taylor

1979-11-09T10:30+0000
Taylor wakes face-down, his dog agitated, the object gone; he is temporarily
unable to speak, his legs hurt, and his truck will not start. He returns home
dishevelled, his thick work trousers torn at the hip, with grazes to chin and
thighs.
witnesses: Robert Taylor · his wife

1979-11-09_to_10
Police accompany Taylor to the site and find ladder-like marks and depressions;
because of the torn clothing and injuries, Lothian and Borders Police record the
matter as common assault and investigate it as a possible crime.
witnesses: Lothian and Borders Police

1979
The site is examined (BUFORA and others); BUFORA later notes the indentations
were 'only in the grass' and 'did not alter the ground profile under the grass' —
inconsistent with a multi-ton craft having stood there.

1992-01
The Livingston Development Corporation installs a commemorative plaque/cairn at
the site (the 'Dechmont UFO Trail').

1994
Steuart Campbell publishes 'The UFO Mystery Solved,' arguing for a
Venus-mirage-triggered temporal-lobe epileptic episode (building on Dr Patricia
Hannaford's symptom reading) and mundane sources for the ground marks.

Named personnel
- Robert 'Bob' Taylor (1919-2007) — Forestry worker (~15 years with the Livingston Development Corporation); a teetotal churchgoer and war veteran, described by all as sincere and non-attention-seeking, who never changed his account; had a history of meningitis ~14 years earlier rank at time: primary witness to: the craft, the spiked spheres, and the attack
- Lothian and Borders Police — Recorded the case as common assault and investigated it — the basis for the 'only UK UFO case subject to a criminal investigation' claim rank at time: role: the criminal investigation
- Steuart Campbell — Skeptic/author; advanced the Venus-mirage + temporal-lobe-epilepsy explanation and mundane ground-mark sources rank at time: role: the leading prosaic account
- Dr Patricia Hannaford — Physician, founder of the Edinburgh University UFO Research Society; proposed the temporal-lobe-epilepsy reading of Taylor's symptoms rank at time: role: the medical hypothesis
- Malcolm Robinson — Scottish ufologist and principal pro-anomaly investigator/chronicler who accepts Taylor's sincerity rank at time: role: the pro-anomaly documentation
Object — reported
shape
a large spherical/domed dark metallic object ('rough like sandpaper') with small propellers set in an outer rim; plus two smaller spiked spheres 'like naval mines' that rolled on legs
size
estimates vary widely — ~7 yards (21 ft) diameter in some accounts to a ~30 ft 'dome' in press reports
surface features
the spiked 'mine' spheres that hooked his trousers; a strong acrid smell ('like burning brakes'); the object vanished while he was unconscious
observed behaviors
- the spheres rolling toward him and dragging him toward the craft by his trousers
- the physical aftermath: ladder-like ground marks and depressions, torn trousers, grazes, temporary aphasia, headache, nausea, raw throat
- on the skeptical reading: an epileptic aura-and-seizure with a structured hallucination, plus pre/post-existing mundane ground marks and a fall
Theories that invoke this case (3)
The face-value reading: a landed craft and device-like spheres that physically assaulted the witness — a daylight landing-and-trace case if the testimony is accepted.
The physical-trace reading: real ground marks, torn trousers, and a stalled vehicle — measurable residue, though its cause is ambiguous (the marks may pre- or post-date the event).
The leading prosaic reading: a temporal-lobe epileptic episode (acrid-smell aura, aphasia, leg weakness, prior meningitis) producing a vivid structured hallucination, with the marks and torn clothing explained mundanely.
Theories that do NOT invoke this case — and why
device-like spheres, not a creature
no associated exotic phenomenology beyond the encounter
a single 1979 encounter, not part of any government-disclosure arc (the police interest was a criminal-assault matter)
Conventional explanations advanced — and their status
A temporal-lobe epileptic episode (with hallucination)
proponents: Dr Patricia Hannaford · Steuart Campbell
The leading prosaic account: the acrid-smell aura, transient aphasia, leg weakness (possible Todd's paresis), headache and thirst, plus prior meningitis, fit a seizure. Weakness: Taylor reportedly never had another seizure, and it does not by itself explain the structured 'mine' imagery or the ground marks. Plausible but unproven (no medical confirmation).
Superior mirage of Venus as a trigger
proponents: Steuart Campbell
Weak: Venus was at only ~3° altitude and the required conditions are unlikely; it does not explain the detailed close-range objects.
Mundane ground marks (utilities, forestry, or post-event fencing)
proponents: Campbell · Metabunk analysts
Plausible: nearby cable ducts, forestry equipment, ladder rung-spacing, or marks from erecting the protective fence afterward; BUFORA noted the marks were only in the grass, inconsistent with a multi-ton craft.
A genuine landed craft and physical attack
proponents: Robert Taylor · Malcolm Robinson
The pro-anomaly reading, resting on the witness's high credibility and the real traces — but with no corroboration of the craft itself (no second witness, photo, radar, or material).
Where further investigation has leverage
- The police assault-case file (and the disputed officer-quote attributions) as the best contemporaneous record.
- The provenance/dating of the ground marks — whether they pre- or post-date the event (utilities/forestry vs. fencing) — which is the unresolved physical question.
- The medical question of whether Taylor's symptoms were a one-off seizure, which can be assessed but not confirmed retrospectively.
Corpus status
under-corroborated
Held under-corroborated. A genuine event with real physical traces and an
unimpeachable witness, but the central claim (the craft and the spiked spheres)
rests on a single observer with zero independent corroboration. It is not a hoax
(the witness's credibility is high), not a settled optical artifact (the
Venus-mirage leg is weak), and not historically-pivotal-explained (the leading
prosaic account — a temporal-lobe seizure — is plausible but unproven, not
demonstrated). The defining feature is the gap between solid documentation of Taylor
and the aftermath and the absence of any corroboration of the phenomenon itself; the
physical traces are real but ambiguous as to cause.
