the machinery does not prove reasonably adequate, and further declaring any agreement contrary to its provisions to be against public policy and void, does not violate the due process clause.[308]
Blue Sky Laws; Laws Regulating Boards of Trade, Etc.--In the exercise of its power to prevent fraud and imposition, a State may regulate trading in securities within its borders, require a license of those engaging in such dealing, make issuance of a license dependent on a public officer's being satisfied of the good repute of the applicants, and permit him, subject to judicial review of his findings, to revoke the same.[309] A State may forbid the giving of options to sell or buy at a future time any grain or other commodity.[310] It may also forbid sales on margin for future delivery;[311] and may prohibit the keeping of places where stocks, grain, etc., are sold but not paid for at the time, unless a record of the same be made and a stamp tax paid.[312] Making criminal any deduction by the purchaser from the actual weight of grain, hay, seed, or coal under a claim of right by reason of any custom or rule of a board of trade is a valid exercise of the police power and does not deprive the purchaser of his property without due process of law, nor interfere with his liberty of contract.[313]
Trading Stamps.--A prohibitive license fee upon the use of trading stamps is not unconstitutional.[314]
Banking
The Fourteenth Amendment does not deny to States the power to forbid a business simply because it was permitted at common law; and therefore, where public interests so demand, a State may place the banking business under legislative control and prohibit it except under prescribed conditions. Accordingly, a statute subjecting State banks to assessments for a depositors' guaranty fund is within the police power of the States and does not deprive the banks of property without due process of law.[315] Also, a law requiring savings banks to turn over to the State deposits inactive for thirty years (when the depositor cannot be found), with provision for payment to the depositor or his heirs on establishment of the right, does not effect an invalid taking of the property of said banks; nor does a Kentucky statute requiring banks to turn over to the protective custody of that State deposits that have been inactive ten or twenty-five years (depending on the nature of the deposit).[316]
The constitutional rights of creditors in an insolvent bank in the hands of liquidators are not violated by a later statute permitting reopening under a reorganization plan approved by the Court, the liquidating officer, and by three-fourths of the creditors.[317] Similarly, a Federal Reserve bank is not unlawfully deprived of business rights of liberty of contract by a law which allows State banks to pay checks in exchange when presented by or through a Federal Reserve bank, post office, or express company and when not made payable otherwise by a maker.[318]
Loans, Interest, Assignments
In fixing maximum rates of interest on money loaned within its borders, a State is acting clearly within its police power; and the details are within legislative discretion if not unreasonably or arbitrarily exercised.[319] Equally valid as an exercise of a State's police power is a requirement that assignments of future wages as security for debts of less than $200, to be valid, must be accepted in writing by the employer, consented to by the assignors, and filed in a public office. Such a requirement deprives neither the borrower nor the lender of his property without due process of law.[320]
