it is commonly assumed that court rulings must be complied with and followed by affected actors in virtually all constitutional systems
but what are the sources of this judicial power? why and when does anyone listen to courts?
following Staton and Moore (2011), we can usefully identify two pillars of judicial power:
autonomy – or independence in a strict sense – or the extent to which judges’ decisions reflect their true preferences as opposed to someone else’s
effectiveness – or compliance – or the extent to which courts can compel actors to comply with adverse decisions
| High Effectiveness | Low Effectiveness | |
| High Autonomy | Powerful Court | Ignorable Court |
| Low Autonomy | Puppet Court | Joke Court |
at the most abstract level the creation and maintenance of a powerful judiciary has been argued to be about credible commitments
by empowering actors (i.e. courts) outside their direct and immediate control, governments signal willingness to be bound by constitutional rules (e.g. respecting property rights) (North and Weingast 1989)
authoritarian regimes want to keep low-level corruption in check
courts can share the blame for unpopular policies (Ginsburg and Moustafa 2008)
independent enforcement of property rights as a credible commitment to investors
courts are useful for controlling opposition movements
courts can provide regime-friendly interpretations of the law, including the constitution
empowering courts comes at a cost to executives and legislators
courts are more stable than governments – empowering courts can insure incumbents against loss of power (Finkel 2005)
powerful courts can make it harder to change policy direction
they can also help protect former leaders and their assets
after winning elections in 1994 president Ernesto Zedillo decided to make the Mexican judiciary more independent and powerful – why?
Finkel (2005) explains this counterintuitive move as a form of insurance policy
the ruling Institutional Revolutionary Party was losing support and anticipated loss of power
the reform gave the Mexican Supreme Court more power to circumscribe (federal and state) government policy

judicial independence is the single most important attribute associated with modern judiciaries
yet there is disagreement on the precise content of this concept
independence to do what? independence from what or whom?
the degree to which judges actually decide cases in accordance with their own determinations of the evidence, the law and justice, free from the coercion, blandishments, interference, or threats from governmental authorities or private citizens. (Rosenn 1987, 8)
can a judge be independent when the judiciary as a whole isn’t?
does “dependence” on another judge’s or court’s decision undermine judicial independence?
what about anticipatory judicial behaviour?
free from “governmental authorities or private citizens”
rulings based on “own determinations of … the law” vs “the law”
many scholars distinguish between “paper” or institutional guarantees of independence and what happens in practice (Melton and Ginsburg 2014; Hayo and Voigt 2007)
the most common de jure guarantees are:
there is mixed evidence on the importance of de jure guarantees of independence on de facto levels
Stiansen (2022) shows that removing re-appointment opportunities made ECtHR judges more likely to rule against the country which nominated them
there is doubt whether judicial autonomy can be measured in isolation due to anticipation effects
Harvey (2022) suggests to focus on contextualizing de facto independence
Toharia (1975) documents that in the authoritarian Spain of the 1970s, judges held diverse opinions different from the regime
ordinary judges were by and large insulated from threat of removal or punishment by the government
however, the regime interfered with independence in politically sensitive cases by creating and staffing a host of special tribunals
General Franco ruled Spain until 1975
Hendley (2022) argues that the creation of special tribunals for political issues is the exception in authoritarian regimes
instead, the “normative” and “prerogative” states coexist side-by-side, often relying on informal institutions
e.g. the same judge handling ordinary cases can be twisting the law to enable the persecution of dissidents
one reason why courts’ autonomy and effectiveness can be high is public support (Carrubba and Zorn 2010)
in general, people hold courts in high regard (Vanberg 2015)
attacking courts and non-compliance is usually politically costly
new courts consolidate power by not antagonizing the government for an initial period
expand jurisdiction through broad interpretation of access rules and legal domains
a common strategy is to first create the power-expanding principle without applying it in the initial case to mitigate costs of compliance
