Good paper re current state procurement rules that prioritize procedural transparency enforced by adversarial legalism in an effort to obtain "low bids" over administrative discretion to choose best value. Potts shows how this has not always been the case and is the result of historic legal drift.

UPDATE: I obtained a copy of the firm-wide email and attachment that Brad Karp, the chairman of Paul Weiss, sent to employees on Thursday evening. The documents detail the agreement Karp reached with the White House before Trump rescinded his executive order targeting the firm.
Dear Members of the Paul, Weiss Community:
We are pleased to announce that President Trump's Executive Order related to our firm was withdrawn a short while ago. We want to share with you the fina! agreement between Paul, Weiss and the Administration - it is attached.
The commitments reaffirmed today are consistent with Judge Simon H. Rifkind's 1963 "Statement of Firm Principles," which states, among other things, that "we believe in maintaining, by affirmative efforts, a membership of partners and associates reflecting a wide variety of religious, political, ethnic and social backgrounds," and that "through this policy we may bring to the service of our clients greater breadth of understanding and wider contacts with the world at large." Judge Rifkind's Statement of Firm Principles closes by saying that "we are committed to achieving our objectives without wearing any client's collar or any political party's livery. And we believe that in the pursuit of these ends we can maintain a law firm in which all who are associated with it may justly take pride." https://www.paulweiss.com/about-the-firm/principles
As a reminder, the firm's policies strictly prohibit firm personnel from speaking to the press or disclosing any confidential information about the firm, whether by posting on social media or otherwise. In addition, given the media attention focused on the firm and the sensitivity of this matter, we request that you refrain from any social media postings or other disclosures relating to the Executive Order or its withdrawäl. Please forward any media outreach to me and our communications director Laura Van Drie
Thank you all for your patience during this time. With this behind us, we can devote our complete focus - as we always do - to our clients, our work, ourStatement by the White House:
Today, President Donald J. Trump agreed to withdraw his March 14, 2025 Executive Order regarding the Paul, Weiss, Rifkind, Wharton & Garrison LLP law firm ("Paul, Weiss*), which has entered into the following agreement with the President:

1. Paul, Weiss agrees that the bedrock principle of American justice is that it must be fair and nonpartisan for all. Our justice system is betrayed when it is misused to achieve political ends.
Lawyers and law firms play a vital role in ensuring that we live up to that standard as a Nation. Law firms should not favor any political party when it comes to choosing their clients. Nor should firms make decisions on whom to hire based on a person's political affiliation. To do otherwise is to deny some Americans an equal opportunity for our services while favoring others.
Lawyers abandon the profession's highest ideals when they engage in partisan decisionmaking and betray the ethical obligation to represent those who are unpopular or disfavored in a particular moment.
2. Paul, Weiss affirms its unwavering commitment to these core ideals and principles and will not deny representation to clients, including in pro bono matters and in support of non-profits, because of the personal political views of individual lawyers.
3. Paul, Weiss will take on a wide range of pro bono matters that represent the full spectrum of political viewpoints of our society, whether "conservative" or "liberal."
4. Paul, Weiss affirms its commitment to merits-based hiring, promotion, and retention. As part of its commitment, it will engage experts, to be mutually agreed upon within 14 days, to conduct a comprehensive audit of all of its employment practices.
5. Paul, Weiss will dedicate the equivalent of $40 million in pro bono legal services over the course of President Trump's term to support these initiatives: assisting our Nation's veterans, fairness in our justice system, the President's Task Force to Combat Antisemitism, and …

This is how DOGE is making our government *less* efficient. Firing the people who conduct the benefit-cost analysis of transportation grants will cause worse decisions. It's penny wise, pound foolish. Their salaries are tiny compared to what they can do to deliver cost savings.
