Definitely interesting reading. Ridiculous in two ways, but interesting.
First, the double containment is ridiculous, pure and simple. An animal with a permit requires double containment for it and all its descendants, in perpetuity. The double containment in itself isn't a problem, realistically. However, the same species without a permit, can be freely bought, sold, and reproduced forever, including movement of eggs across state lines. Foolish double standard which effectively DIScourages use of permits.
Second, the Lacey Act does not in fact, in text, or in original proposals, prohibit interstate movement of injurious species. So despite USFWS claims...they're wrong...
"The injurious species provision prohibits “the importation into the United States ... or any shipment between [the States]” of any listed animals, their offspring, or eggs." [
http://nationalaglawcenter.org/wp-content/uploads/assets/crs/R43170.pdf page 1]
This BEGINS to help, but as I'll point out later, is abbreviated in a way which actually further detracts from what the law truly says. A first point is the use of "shipment". As the same document discusses, "However, there is a legal question as to whether FWS’s interpretation of the injurious species ban properly extends to transport, rather than only to import and shipment, as stated by the law" [summary]. Court precedent, and guidelines followed for passing judgement, dictate that when wording must be clarified, the following must be considered: 1) where terms are defined within the law, those definitions must be applied. When there is differential usage, those differences must be maintained. "Shipping" is defined and applied in contexts which exclusively involve commercial movements. "Transport" is used in contexts in which movements are not limited to commerce. Lacey Act says "shipping", USFWS says "transport", and they're NOT the same thing [see also page 6, 13, and other sections of above]. 2) where the wording is otherwise vague, does the government [ie, USFWS] interpretation fall within acceptable interpretation? I would say "no", but in this case the wording isn't vague, so the question is moot. 3) if the wording is vague, congressional intent must be considered. Did Congress INTEND to ban all interstate movements of "injurious species"? No, they did not. The first quote I provided above is part of the problem - it's incomplete and thus obscures the true intent and meaning of the law, which reads more completely thus; "The importation into the United States, any territory of the United States, the District of Columbia, the Commonwealth of Puerto Rico, or any possession of the United States,
or any shipment between the continental United States, the District of Columbia, Hawaii, the Commonwealth of Puerto Rico, or any possession of the United States, of the mongoose of the species Herpestes auropunctatus; of the species of so-called “flying foxes” or fruit bats of the genus Pteropus; of the zebra mussel of the species Dreissena polymorpha; of the bighead carp of the species Hypophthalmichthys nobilis; and such other species of wild mammals, wild birds, fish (including mollusks and crustacea), amphibians, reptiles, brown tree snakes, or the offspring or eggs of any of the foregoing which the Secretary of the Interior may prescribe by regulation to be injurious to human beings, to the interests of agriculture, horticulture, forestry, or to wildlife or the wildlife resources of the United States, is hereby prohibited."
Nowhere does it say "transport". In fact, nowhere does it say "between the states" either. It specifies four places and one category of places between, but not within, which shipping is barred. Only one state, which is part of the USA, but not part of CONUS [military - "CONtinental US] is mentioned by name. The remainder are part of a single unit which you cannot "ship" into. Shipping between Montana and Guam is illegal. Shipping [or transport] between Pennsylvania and Arizona, is not, since both are within CONUS and there is no shipping between the single entity "continental United States" and elsewhere. See also PIJAC submitted comments and similar SBA comments (
https://www.sba.gov/sites/default/files/Bsal_in_Salamanders_Comment_Letter.pdf). It's worth noting that in 1974, a USFWS representative testified in favor of this interpretation, which was followed by USFWS in the 1970s. The District Court for DC has also recently rejected current USFWS interpretation, in their temporary injunction favoring USARK and certain python and boa breeders. From USARK's case (
http://usark.org/wp-content/uploads/2015/04/USARK_Memoradum_of_Law_in_Support_of_PI-4.1.15.pdf) "FWS special agent-in-charge Richard Parsons explained that, “there is no restriction
that we find in section 42 of the Lacey Act to interstate shipments, with the possible exception of restrictions from areas off the continental United States, such as Puerto Rico, the Virgin Islands, and Hawaii.”"
See footnotes from the latter two documents for the actual propositions before Congress in 1974/1975 - they're absolutely clear that the ban would not apply to transport between the 49 continental states. Both documents are interesting and informative reading in their wholes.
A further point, which is perhaps not worth even getting into [also discussed in Tim Hermann's submitted comments and in the last two documents] is the point that the "injurious species" provisions were initially and explicitly "foreign". While the word "foreign" was later dropped, the intent was not: any attempt to expand the law to specifically apply to native species was rejected. Consequently, there is no indication that a native species [Taricha, Siren, Plethodon, Notophthalmus, etc.] may actually legally be designated 'injurious'.
So, on the whole, I would conclude that if you transport, or even "ship" an 'injurious' salamander within the 49 continental United States [especially a native species, but excepting other illegal activities tied to the animals], you would not be in violation of the Lacey Act. Sure, USFWS MIGHT [if they have the resources...resources which only allow them 1 or 2 people per year to research injurious species] confiscate, 'charge', and prosecute you...but you would not be breaking the law.
