It is not required to have parental consent to transport a minor from state to state. However, under 18 USC 2423(a)
A person who knowingly transports an individual who has not attained
the age of 18 years in interstate or foreign commerce, or in any
commonwealth, territory or possession of the United States, with
intent that the individual engage in prostitution, or in any sexual
activity for which any person can be charged with a criminal offense,
shall be fined under this title and imprisoned not less than 10 years
or for life.
The new proposed provision expands the definition of "human trafficking" to include
(vi) Recruiting, harboring, or transporting a pregnant minor with the
intent to deprive the pregnant minor's parent of knowledge of, and to
procure, a criminal abortion, as described in section 18-622, Idaho
Code.
Human trafficking is later deemed to be a crime, but also violation of that crime under subsection (vi) is punished by 2-5 years in prison rather than 25 years.
Note that §1 of the bill also gives a definition of "criminal abortion":
(4) "Criminal abortion" means a violation, an attempted violation, or
a threatened violation of section 18-622, Idaho Code
The inclusion of threat extends the threat of criminal punishment in unconstitutionally vague ways, because for this subsection to be effective, it would have to expand "violation of section 18-622" by some magic. §18-622 simply says that
Every person who performs or attempts to perform an abortion as
defined in this chapter commits the crime of criminal abortion.
A person who transports does not violate §18-622, therefore a person to threatens to transport also does not violate §18-622.
It is nonsensical to speak of "procuring a crime", yet that is what the bill says. "Criminal abortion" is the (criminal) act of obtaining an abortion, and abortion is defined in §18-604 as
the use of any means to intentionally terminate the clinically
diagnosable pregnancy of a woman with knowledge that the termination
by those means will, with reasonable likelihood, cause the death of
the unborn child except that, for the purposes of this chapter,
abortion shall not mean the use of an intrauterine device or birth
control pill to inhibit or prevent ovulations, fertilization or the
implantation of a fertilized ovum within the uterus.
It is meaningful to speak of "procuring an abortion", but "criminal abortion" is given a special legal definition.
The criminal act defined in
§18-622 criminalizes performance of an abortion in a fashion contrary to law, where §18-622 also defines defenses to a criminal charge.
To be convicted, it would (theoretically) be necessary to prove two intents: deprive the parents of knowledge (text them before you go!) and procuring a criminal abortion. We may assume that if this wording stands, the courts will have to discover a legislative intent to say that "criminal abortion is deemed to be equivalent to abortion", despite the fact that the law does not actually say that.
One cannot appeal to the ordinary meaning of words to interpret this clause.
In traveling to Washington for an abortion, one does not obtain a "criminal abortion", one obtains a legal abortion. A person being transported to Washington or Oregon for an abortion is not procuring an illegal / criminal abortion, they are procuring a legal abortion.
This is not to say that they couldn't fix the wording, though it's only the federal government that has the exclusive right to regulate interstate commerce. The US could then sue to block enforcement of this law.
