Comparing Cert Stage OSG Efforts Under Obama and Trump

The Office of the Solicitor General (OSG) is involved in more Supreme Court litigation on a yearly basis than any other entity. The OSG also plays a unique role in this litigation as its team provides the Court with information, which is oftentimes related to the incumbent administration’s policy views.  This singular position has been written about at length in various books and articles including Rebecca Salokar’s expansive 1994 work The Solicitor General: The Politics of Law.

Empirical work on the OSG has revealed additional details about the relationship between the Court and the OSG.  Thompson and Wachtell’s article looking at the OSG’s certiorari petition procedures, for example, shows that when the Court requested a response from the United States in OT ‘04, the likelihood of a cert granted rose from .9% to 8.6%.  Empirical SCOTUS previously ran a piece that showcased the OSG’s participation at the Supreme Court in terms of number of filings and another that looked at various administration’s OSG success in Supreme Court cases on the merits.

This piece examines various modes of OSG participation in the Supreme Court at the cert stage for a subset of cases from the OSG under Obama and the OSG under Trump. In the end this shows that the Court has responded differently at times to the two OSGs and presents possibilities for reconciling these differences including divergent policy views and procedures.

The main source of data for these analyses is the OSG’s website which houses a substantial number of the OSG’s Supreme Court filings from the past decade or so.

Cert Petitions

The OSG’s website contains 42 cert petitions from Trump’s OSG through the beginning of May 2019 including ten still pending a response from the Court. 56 petitions from Obama’s OSG were randomly selected as a comparison group. The first figure shows the different petition/case issue areas for these petitions as coded by the OSG.

This figure shows some initial differences in foci of the two OSGs as the Trump sample is weighted more heavily towards immigration and criminal/habeas cases.  The OSG under Obama shows a bit more parity in terms of petition type with a high relative number of filings in areas like labor and employment and natural resources.

How did these petitions fare? Even though the sample is smaller for the petitions from Trump’s OSG, below are some preliminary comparisons and results. The top level columns show the raw numbers of petitions while the lower level columns show the relative percentages for the two administration’s OSGs.  The abbreviation GVR stands for grant, vacate, and remand and means the Court both grants the petition and sends it back to the lower court, generally for review based upon a new controlling decision.


This figure show that Obama’s OSG had greater success with petition grants with a lower rate of denials even when excluding Trump’s OSG petitions currently pending. When the pending petitions are removed, Trump’s OSG grant and deny rates both increase to 40.63% which are lower than Obama’s OSG grant percentage and higher than Obama’s OSG deny percentage. When we combine the grants and GVRs, the grant percentages are quite similar with Obama’s OSG combined percentage just over Trump’s at 62.5% compared with 59.38%.

Another area of difference is in the time it took the Court to render a decision on the OSGs’ petitions.


While the Court took about ten more days on average when it granted a Trump OSG petition than when it granted an Obama OSG petition, the times were much lengthier for the Court to deny or GVR an Obama OSG petition.  These numbers were elongated by several petitions that skewed the results for the Obama OSG petitions. In Shanahan v. Lora for instance, the OSG filed a petition on March 25, 2016 but the Court did not come back with a GVR until March 5, 2018 or 710 days later. Similarly Obama’s OSG filed a petition in Lynch (later changed to Sessions) v. Magana-Pena on June 10, 2016. The Court waited 703 days to deny the petition on May 14, 2018.


In a non-insignificant number of instances, the Court requests the OSG’s views on whether it should grant cert in a case. The procedure known as calling for the views of the Solicitor General or CVSG conveys the trust the justices place in the OSG’s assessment of cases and whether they are proper for Supreme Court resolution.  The OSG responds with a cert-stage amicus brief in such cases, generally either recommending the Court grant or deny the petition. The Court’s subsequent responses, either according with or diverging from the recommendations of the OSG further illustrate the proximity of the relationship between the OSG and the Court at certain points in time.  Amy Howe recently reviewed several of the recent CVSG responses from Trump’s OSG for SCOTUSBlog.  These did not make it into this analysis since the Court has yet to come back with a decision on cert in these cases.

This is one area where the OSG under Trump has performed much better than the OSG under Obama as the figure below shows. The CVSG counts are on the left column and the relative percentages are on the right. These figures are based on 41 CVSGs where the Court has decided on cert under Trump’s OSG and 53 CVSGs under Obama’s OSG.

According to the invited cert amicus briefs section of the OSG’s website, by the middle of May 2019, the Court has yet to deny a petition that OSG under Trump recommended the Court grant after a CVSG. The OSG under Obama was also highly successful in this regard with a 92% grant rate based on recommended grants. A big difference is evident from when the two OSGs recommended the Court deny petitions. In such cases the Court agreed with assessment of Trump’s OSG 92% of the time while it only agreed with Obama’s OSG 65% of the time. Without reading too much into this differential, it seems safe to say that the justices either agreed with the OSG under Trump more frequently (at least so far) or puts greater faith in the recommendations of Trump’s OSG.

When we look at the CVSG filing time differences between administration’s OSGs and the Court’s subsequent decisions on cert, the differences are only slight.


Two interesting points to note from these graphs are that the OSG under Trump took an average of about nine days longer to file CVSGs after a request from the Supreme Court than the OSG under Obama (level two of the figure). Secondly once the OSG’s amicus brief was filed, the Court responded with a cert decision about four days faster for Trump’s OSG than it did for Obama’s OSG (level four of the figure).


A final way that the OSG participates in cert is by responding to cert petitions. Due to the large number of petitions where the U.S. is listed as the respondent, the OSG does not immediately file responses in all cases and instead waives the right to respond in many. In a handful of cases where the OSG waives a response, the Court decides that a response from the OSG would be helpful and calls for a response (a process known as a CFR).

Another nuance of petitions is that indigents who cannot afford the Court’s filing fees can have the fees waived. Such petitions are known as in-forma pauperis or IFP. IFP petitions tend to have an appreciably lower success rate on cert than paid petitions.

The set of responses taken from the OSG’s website initially contained a random set from each administration’s OSG where the Court had rendered a decision on cert.  This random set only contained paid responses, however. Trump’s OSG cert responses were comprised of 18 responses to CFRs and 84 responses without the response waived. Obama’s OSG cert responses were made up of 13 responses to CFRs and 88 responses without a waiver.  To examine CFR statistics in a bit more detail I randomly added 30 cases with CFRs under Obama’s OSG and 30 under Trump’s OSG.  Of these responses, 25 were to IFP petitions and five were to paid petitions for Trump’s OSG and 27 were to IFP petitions and three to paid petitions for Obama’s OSG.

Both administrations’ OSGs were successful in preventing cert in a large majority of these cases although Obama’s OSG was a bit more successful overall.


The Court denied cert in 92.6% of cases with IFP petitions where Obama’s OSG filed a response. Note that many of these were based on responses to CFRs which raise the likelihood of a grant. The Court also denied 87.5% of paid petitions when Obama’s OSG filed a response. The Court denied paid petitions at a similar rate for Trump’s OSG at 90.57%. A greater percentage of IFP petitions were granted or GVRed after Trump’s OSG responded to the petitions leaving the denial rate at 76% or about 15% lower than that for Obama’s OSG.

When the CFR cases were isolated, one of the results was quite surprising.


Out of the 16 paid cases with CFRs under Obama’s OSG and 23 paid cases with CFRs under Trump’s OSG, all petitions were denied. This inevitably relates to the sample of paid CFR responses drawn, but shows that a CFR in a paid case does not always enhance the likelihood of a grant, especially in recent years. Since all of the IFP filings in the overall responses were also in response to CFRs (the OSG website did not initially include IFP responses in the random sample of selected) the numbers for IFP response are the same here as they are in the figure for all responses as both show a higher deny rate for Obama’s OSG than for Trump’s OSG.  Although there is no separate set of responses to IFP petitions without CFRs in this analysis, the OSG almost always waives the right to respond to IFP petitions and has historically had a very high rate of denials when it responds in IFP cases without CFRs.

The bulk of these statistics are surprisingly similar for Obama’s OSG and for Trump’s OSG. The most telling difference between the two is the Court’s responses to amicus briefs filed in response to CVSGs. The differences in the Court’s adherence to recommendations from Trump’s OSG over Obama’s OSG, especially when Trump’s OSG recommended the Court deny cert implies a higher level of trust for the current administration’s OSG. These rates will obviously fluctuate as Trump’s OSG weighs in on more petitions and so by the end of this administration’s time in office we might well see differences from what we have today. At this point though, this difference may illuminate a key distinction between the Court’s relationship with Trump’s OSG and with Obama’s OSG.
