## Why It Matters
Law No. 3187 of June 28, 1957, represents a specific mechanism of Brazilian economic policy during the Juscelino Kubitschek administration. By extending the "regime of license" for commercial exchange, the law illustrates the government's direct control over imports and exports through licensing requirements rather than allowing completely free trade. This type of prorogation (extension) was a standard legislative tool used to maintain continuity in trade regulations while broader economic policies were being developed or adjusted.

As a statutory instrument, it exemplifies the function of a statute as the "manifestation of statutory law"—serving as the concrete, written evidence of a rule that governs society. While the extension was brief (extending validity only to July 31, 1957), it demonstrates the ongoing administrative management of Brazil's foreign trade relations during a period of significant industrialization and economic change in the late 1950s.
