temporary restraining order against the demonstrators on December 15.   After a hearing held
several months later, the temporary injunction was made permanent.

The defendants, represented by W.A.C. Hughes and Warner T. McGuinn, appealed to the
Maryland Court of Appeals. They argued that picketing in labor disputes could not be enjoined
under Maryland law. In Green v. Samuelson. the Court of Appeals responded that "in our
opinion, this is a racial or social question, and as such, the rules heretofore announced and
applied to labor disputes have no application.""4 The Court of Appeals acknowledged "That
there is some merit in their complaint cannot be disputed, as the planting of a white store in an
exclusively colored community is an exploitation of the inhabitants for profit, but the defendants
cannot right their wrongs by means that are unlawful."115 The Court affirmed the injunction with
respect to the pickets, but reversed it to the extent that it restrained defendants from doing
anything that might tend to injure the plaintiffs' business. The opinion then listed the permissible
conduct for persuading merchants to hire black employees:

They may, by organization, public meetings, propaganda, and by personal
solicitation, persuade white employers to engage colored employees and induce
their people to confine their trade to those who accede to their wishes, and
whether they succeed or fail will depend on the co-operation of their people.116

The "Don't Buy Where You Can't Work" movement had a significant initial success,
bringing together a broad coalition that would shortly mobilize to attack a wider span of
discrimination. It also produced disagreement. Opponents argued that it tended to deepen a
segregated society and was ultimately of little economic effect.117 Despite the disagreement over
tactics to improve black employment and the impact of the injunction, the boycott did open
employment opportunities within the retail stores serving the black community. Employment
elsewhere raised further obstacles. Creating employment opportunities in businesses in the
private sector where the black community did not have any economic leverage required support
from whites. Job opportunities in the public sector, however, might be opened by reliance on
the Constitution.

After the opening of the Maryland Law School to black students, described in the next
section, Thurgood Marshall brought a series of cases to secure equal pay for black teachers in the
black schools. Several counties raised pay for black teachers as soon as suit was filed and the
Governor apparently conceded that the disparity was unconstitutional."8 One case that
proceeded to decision, Mills v. Bd. of Education of Anne Arundel County."9 held that the
petitioner was entitled to relief.

Constitutional rights, however, depended on showing that the state was responsible for
the discrimination. This was not always easy. In 1943 Louise Kerr was refused admission to a
library training class conducted by the Pratt Library to prepare persons for staff positions. She
sued in federal district court for damages and an injunction. Charles Houston represented her
(W.A.C. Hughes was on the brief). The district court judge, Calvin Chestnut, held that the Pratt
