In form it was simply an injunction on a plaint. When for some reason right could not be obtained by the means afforded by the common law, the injured party had to apply to the king by petition. One of the most common cases was when redress was sought for some act of the king himself or of his officers, when the consequent injunction to the common law courts or to the Exchequer to examine the case invariably began with the identical formula which gave its name to the writ by which privileged villains complained of an increase of services; monstravit or mons traverunt N. N.; ex parte N. N. ostensum est: -- these are the opening words of the king's injunctions consequent upon the humble remonstrations of his aggrieved subjects.(49*) Again, we find that the application for the writ by privileged villains is actually described as a plaint.(50*) In some cases it would be difficult to tell on the face of the initiatory document, whether we have to do with a 'breve de monstraverunt' to coerce the manorial lord, or with an extraordinary measure taken by the king with a view to settling his own interests.(51*)And this brings me to the main point. Although the writ under discussion seems at first sight to meet the requirement of the special case of manors alienated from the crown, on closer inspection it turns out to be a variation of the peculiar process employed to insist upon a right against the crown. Parallel to the 'Monstraverunt' against a lord in the Common Pleas we have the 'Monstraverunt' against the king's bailiff in the Exchequer.
The following mandate for instance is enrolled in the eventful year 1265: 'Monstraverunt Regi homines castri sui de Brambur et Schotone quod Henricus Spring constabularius castri de Brambur injuste distringit eos ad faciendum alia servicia et alias consuetudines quam facere consueverunt temporibus predecessorum Regis et tempore suo. Ideo mandatum est vicecomiti quod venire etc. predictum Henricum a die Pasche in xv dies ad respondendum Regi et predictis hominibus de predicta terra et breve etc.'(52*)There is not much to choose between this and the enrolment of a 'breve de monstraverunt' in the usual sense beyond the fact that it is entered on a Roll of Exchequer Memoranda. In 1292 a mandate of King Edward I to the Barons of the Exchequer is entered in behalf of the men of Costeseye in Norfolk who complained of divers grievances against Athelwald of Crea, the bailiff of the manor. The petition itself is enrolled also, and it sets forth, that whereas the poor men of the king of the base tenure in the manor of Costeseye held by certain usages, from a time of which memory runs no higher, as well under the counts of Brittany as under the kings to whom the manor was forfeited, now bailiff Athelwald distrains them to do other services which ought to be performed by pure villains. They could sell and lease their lands in the fields at pleasure, and he seizes lands which have been sold in this way and amerces them for selling; besides this he makes them serve as reeves and collectors, and the bailiff of the late Queen Eleanor tallaged them from year to year to pay twenty marks, which they were not bound to do, because they are no villains to be tallaged high and low.(53*) Such is the substance of this remarkable document, to which I shall have to refer again in other connexions. What I wish to establish now is, that we have on the king's own possessions the exact counterpart of the 'breve de monstraverunt.' The instances adduced are perhaps the more characteristic because the petitioners had not even the strict privilege of ancient demesne to lean upon, as one of the cases comes from Northumberland, which is not mentioned in Domesday, and the other concerns tenants of the honour of Richmond.
There can be no doubt that the tenantry on the ancient demesne had even better reasons for appealing to immemorial usage, and certainly they knew how to urge their grievances. We may take as an instance the notice of a trial consequent upon a complaint of the men of Bray against the Constable of Windsor.
Bray was ancient demesne and the king's tenants complained that they were distrained to do other services than they were used to do. The judgment was in their favour.(54*)The chief point is that the writ of 'Monstraverunt' appears to be connected with petitions to the king against the exactions of his officers, and may be said in its origin to be applicable as much to the actual possessions of the crown as to those which had been granted away from it. This explains a very remarkable omission in our best authorities. Although the writ played such an important part in the law of ancient demesne, and was so peculiar in its form and substance, neither Bracton nor his followers mention it directly. They set down 'the little writ of right close' as the only writ available for the villain socmen.
As the protection in point of services is nevertheless distinctly affirmed by those writers, and as the Monstraverunt appears in full working order in the time of Henry III and even of John,(55*) the obvious explanation seems to be that Bracton regarded the case as one not of writ but of petition, a matter, we might say, rather for royal equity than for strict law. Thus both the two modes of procedure which are distinctive of the ancient demesne, namely the 'parvum breve' and the 'Monstraverunt,' though they attain their full development on the manors that have been alienated, seem really to originate on manors which are in the actual possession of the crown.
If we now examine the conditions under which the manors of the ancient demesne were alienated by the crown, we shall at once see that no very definite line could be drawn between those which had been given away and those which remained in the king's hand.
