A legal battle between the Chapter of St. Servaas and Willem II of Horn

A legal dispute between the chapter of St. Servaas and Willem II of Horn over rights and land ownership in Weert in 1295.

On September 21, 1062, the Roman Catholic King Henry IV, in the presence of a number of imperial magnates, confirmed a grant by Otto, Count of Thuringia, and his wife Adela of an estate—including properties and rights in Dilsen and Weert—to the Chapter of St. Servatius in Maastricht (charter no. 1).

This grant was subsequently challenged by William II of Horn (1245–1300), who sought to expand his secular power in Weert and the surrounding area. His infringements on the chapter’s rights forced the chapter to file a lawsuit against William II with the ecclesiastical court in Liège, which issued its ruling on May 21, 1295 (charter no. 75).

This statement is notable in that it provides a comprehensive overview of the Roman-canonical procedure as it was commonly practiced at the end of the 13th century before the ecclesiastical court in Liège, as well as the legal peculiarities that came to the fore.

Why was the chapter’s complaint brought before an ecclesiastical court rather than a secular one? The answer lies in the Church’s universal jurisdiction over all matters in which the Church’s interests were at stake: the so-called causae spirituales and causae spirituales annexae, spiritual matters (pastoral care) and related matters (including the Church’s material rights).

Why was the Roman-canonical procedure followed? The Church operated under Roman law and essentially followed the procedural law of the late Roman imperial period, the inquisitorial procedure—a rational procedural form in which the determination of substantive truth was central and the judge played an active role. In this respect, ecclesiastical jurisprudence differed from secular jurisprudence, which for a long time still used the accusatory form of procedure, in which the judge was passive and the parties settled their dispute by taking oaths and invoking divine judgments.

In the charter dated May 21, 1295, the ecclesiastical judge of the Diocese of Liège provides a step-by-step account of the proceedings between the chapter and Willem of Horn, before rendering his judgment. Essentially, the dispute boils down to this: the chapter accuses Willem of Horn of infringing upon the chapter’s rights in Weert. The chapter demands that he refrain from doing so in the future and that he compensate the chapter for the loss of income it has suffered. The defendant, Willem of Horn, of course denies the chapter’s complaint and states, on the contrary, that he was traditionally entitled to do so.

The chapter therefore asked the judge of the ecclesiastical court to administer justice, especially since Willem of Horn was said to have already admitted his wrongdoing in the presence of righteous people.

Willem of Horn replies in court that the chapter’s complaint is unfounded and that he possesses full jurisdiction in Weert. He cites open and peaceful possession for more than sixty years by himself and his predecessors, the Counts of Horn and Altena. If the chapter and their witnesses dare to claim otherwise, they are committing perjury and giving false testimony. He therefore demands that the judge declare the complaint unfounded and that the chapter be ordered to pay the costs.

Once the basis for the litigation(litiscontestatio) had thus been established, witnesses were heard and cross-examined by both sides. The chapter’s procurator argued that Willem of Horn, contrary to the rules of canon law, had permitted witnesses to be heard in Weert and other locations deemed suspect by the church, the deacon, and the chapter, even though these witnesses could easily have traveled to Liège to give their testimony before the ecclesiastical judge. The chapter therefore claimed that the witness statements in favor of Willem of Horn were null and void. Moreover, there were allegations of coercion and bribery. In addition, Willem of Horn was said to have threatened witnesses who wanted to testify in favor of the chapter. Because Willem’s witnesses were people of ill repute, frivolous and perjured, including fornicators, adulterers, and ecclesiastically excommunicated persons, the chapter asked that their statements be declared invalid.

To prove their claim, the chapter produced the original deed of grant dated September 21, 1062.

In response, Willem of Horn’s attorney stated that his client did not dare come to Liège in person due to mortal danger, unsafe roads, and political unrest, and requested that the judge of the ecclesiastical court provide him with a safe place where he could appear in person to plead his case. The judge granted that request and designated Maastricht as the location to continue the case, instructing Master Gilles of Liebertenges to temporarily replace him as judge.

Afterward, when the judge of the ecclesiastical court resumed his duties as presiding judge, Willem of Horn declared that the proceedings in Maastricht were invalid, whereupon he demanded that the chapter’s claim be dismissed and that it be ordered to pay the costs of the proceedings.

Thereupon, the judge of the ecclesiastical court once again delegated his duties to a substitute, Master Henneman, a lawyer from Liège practicing in Maastricht, who ruled against Willem of Horn in an interim judgment; following this, his attorney appealed to the Liège judge of the ecclesiastical court, who upheld Master Henneman’s judgment.

At this point, Willem of Horn went on the offensive, claiming that the chapter had no authority to bring a lawsuit against him, since the deacon and the chapter were allegedly excommunicated to the highest degree. In an interim ruling, the judge of the ecclesiastical court then determined that Willem of Horn had not proven the alleged excommunication and ordered him to pay the costs.

This again went against Willem of Horn’s wishes, and he initiated new proceedings against the chapter over this matter, until the judge of the ecclesiastical court ruled on this issue as well and determined that the trial regarding the chapter’s original claim should continue.

On the day of the final judgment, Willem of Horn was absent. Nevertheless, on the grounds that the divine presence compensated for Willem of Horn’s absence, the judge of the ecclesiastical court ruled in favor of the chapter. He prohibited Willem of Horn from further infringing on the chapter’s rights in Weert and ordered him to pay damages and litigation costs.

Willem of Horn was clearly dissatisfied with this verdict, and his successor, Gerard of Horn (1300–1331), subsequently brought the case before ecclesiastical arbitrators in Utrecht, who recorded their decision in a new charter on December 19, 1306.
