How does this type of process aid our legal system?

Third Party Beneficiaries
Introduction:
Contracts may be written to benefit a third party. The law recognizes that third parties who are intended beneficiaries have the right to enforce the contracts.

Concept Review:
An intended beneficiary is a third party to a contract whom the contracting parties intended to benefit directly from their contract.
Case:
Please read CASE 13-3: Lawrence v. Fox, 20 N.Y. 268 (1859).
Critical Thinking Question: Form an opinion about the contemporary relevance of this ruling. Given the widespread and extremely significant changes in U.S. society and the world over the past 150 years, what is the justification for consideration of such an old case? How does this type of process aid our legal system? How might it detract from the reasonableness of modern deliberations? Please remember to define promisor, promisee, and intended beneficiary in your discussion.
