Abstract
It can be difficult to approach and effectively describe a large body of individual decisions involving a range of unique circumstances and issues, such as CAS jurisprudence. A balance between overwhelming complexity and oversimplification must be struck carefully. One approach for doing so is to treat CAS’s body of decisions as a network connected through references. Studying such a network allows for the detection of the basic structure of CAS jurisprudence, of how CAS relates to its own previous decisions, and how this has developed over time. In this chapter we will explore the basic structure of CAS jurisprudence but also more generally how CAS operates and interacts with the cases that come before it and with its previous decisions.

Below we will be returning to this question and exploring more generally whether there is correlation between the characteristics of individual CAS decisions and their precedential and persuasive power , which is essentially the same type of inquiry applied to the entire data.

Another element of the strength of the network is the strength of the connections between its components. For example, a pair of arbitrators that have appeared on the same CAS panel many times together can be said to be more strongly connected than a pair that only appeared once on the same panel. See further Sect. 8.4. In the network this can be represented in the weight of the edge connecting two vertices .

See above Fig. 3.5 Network Density Over Time. Note that time is here measured in edges , i.e. references between CAS decisions in chronological order, rather than some more conventional time measurement. The main reason for and advantage of using edges as a time measurement is that it is independent of changes in the average number of decisions or references, which in CAS have been quite significant. It should be noted that the figure does not take into consideration islands for the purpose of calculating the density of the CAS case law network.

Lupu and Voeten 2011. Excluded from this is 3,950 cases that were disposed by through so-called pilot procedures. It should be noted that Lupu and Voeten only consider decisions issued by the ECtHR until 2006 and the numbers are thus somewhat outdated. However, for the purpose of comparing how connected two legal citation networks are at a given point in time and at a particular size, these numbers provide adequate information.

In fact, there is somewhat of a bias in the opposite direction: the fewer previous decisions the court has, the less likely it is that there is one decision that is relevant to cite. However, the impact of this connection to network size is much smaller than the one for density since it only takes citing a single decision to be included in the network.

Milgram 1967. Milgram’s study does not actually make or support a claim regarding the distance of the global population. However, subsequent empirical studies suggest that it may not be entirely erroneous. See e.g. Leskovec and Horvitz 2008 (the average user distance on MSN Messenger is 6.6 degrees); Kwak et al. 2010 (the average user distance on Twitter is 4.1 degrees); Viswanath et al. 2009 (the average user distance on Facebook is 3.7 degrees).
- 44.
Which explains why the notion is often referred to simply as six degrees of separation.
- 45.
This obviously does not include islands .

See below Fig. 3.7 Doping Sub-Network. This sub-network consists of 1,269 edges (citations) connecting 383 vertices (CAS decisions). 46 unconnected vertices (islands ) are not represented in order to increase the figure’s legibility.

These fluctuations are in part a result of the small sample size during those early years, but a contributing factor may also be a shift in how CAS deals with cases that are successfully conciliated. Until 1999, those cases were terminated by issuing a termination order, but since then they result in a consent award. Mavromati and Reeb 2015, p. 308.

In most CAS decisions, this date is explicitly stated as part of CAS’s presentation of the procedural history of the case. Where the filing date was unclear, the decision was disregarded for the purpose of calculating the length of the procedure. The dataset contained a total of 817 CAS decisions where the procedure length could be determined with certainty.

See above Fig. 3.13 CAS Procedure Length Over Time. The figure shows that the average length varied significantly year-by-year from 1985 to 2002. However, it should be noted that the number of decisions during those years were quite low and that the length of the procedure in individual cases may thus have a disproportionally large impact on the yearly mean.

And most other time-directed networks for that matter.
- 148.
See the model distribution above in Fig. 3.15 Indegree Centrality Over Time. The model was constructed by taking all outwards references actually made in CAS decisions and assuming (contrary to what actually happened) that inwards references were distributed equally among all prior decisions in existence when the references were made.
- 149.
See above Sect. 3.5.
- 150.
I.e. the oldest decision’s outdegree centrality must be zero.
- 151.
I.e. the most recent decision’s indegree centrality must be zero.
- 152.
See above Fig. 3.15 Indegree Centrality Over Time.
- 153.
Also, remember that indegree unlike outdegree can and in fact does change continuously over time.
- 154.
This assumption is of course not necessarily reasonable if there is other evidence to the contrary. However, at least with regard to the particular case of CAS’s 2013–2014 jurisprudence I am not aware of any such evidence.
- 155.
It is worth emphasizing that what we are measuring here is the CAS’s general approach throughout its entire history to all of its decisions and which seems to follow rather specific patterns. However, if one were to study individual CAS decisions one should expect to find deviations from these patterns, sometimes quite extensive ones.
